This method has been developed to determine trace levels of phthalate esters, including diethyl phthalate, benzyl butyl phthalate, and di-iso-butyl phthalate in urine, blood plasma, tap water, and groundwater samples. The natural deep eutectic solvents were prepared using terpenoid-derived natural compounds containing menthol and camphor in various ratios. The HF-SLPME device was constructed by reinforcing and immobilizing the synthesized Fe₃O₄-MWCNTs within the pores of a 2.5 cm segment of hollow fiber microtube through ultrasonication, followed by filling the lumen with the natural deep eutectic solvent with both ends heat sealing. The extraction process was conducted in direct immersion mode. Values of crucial variables for HF-SLPME were optimized through a multivariate methodology based on a central composite design, with 30 extraction tests performed to determine the best conditions. The method exhibited good linearity (correlation coefficients <i>R</i>² &gt; 0.996) over a dynamic range lower than 0.927–10³ µg L⁻¹. The results show that the limits of detection/quantification for the chosen PEs ranged from 0.19 to 0.27/ 0.65 to 0.92 µg L⁻¹ with enrichment factor˃ 37.24. As evidenced by intra- and inter-day precisions, satisfactory reproducibility was achieved with relative standard deviations (RSDs) below 3.7% and 5.1%, respectively. The recoveries of the selected phthalate esters from spiked real samples ranged from 88.4 to 111.1%, with relative standard deviations between 2.3 and 6.5%. This HF-SLPME-HPLC–DAD method offered a new, cost-effective, sensitive microextraction approach for determining and quantifying phthalate esters in aqueous samples with complex matrices.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"78 18","pages":"9415 - 9433"},"PeriodicalIF":2.2,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142737290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, membrane fouling is a significant impediment in this regard, as it reduces the quality and quantity of water produced, increases energy consumption, requires cleaning, and shortens membrane life. The use of granular activated carbon (GAC) adsorption in conjunction with ultrafiltration (UF) as a pre-treatment ensures that high-quality seawater enters the desalination process free of contaminants that could harm the plant. This method increases the efficiency and longevity of the equipment, lowers maintenance costs, and produces high-quality desalinated water for a variety of applications. In this study, GAC was made from commercially available charcoal and used to remove organic compounds, heavy metals, and microbiological contaminants from seawater. A preliminary study was conducted to determine GAC’s effectiveness in removing methylene blue (MB). The removal efficiency was found to be 78 and 99% at initial MB concentrations of 50 and 10 mg/L, respectively. The isotherm modeling confirms that the adsorption process follows the Langmuir model. In addition, the kinetic study demonstrated that MB adsorption on GAC follows the pseudo-second-order model. GAC filtration removed more than 99% of COD and significantly reduced metal concentrations such as Zn, Cu, and Cd. Bacteriological analysis of seawater treated with GAC revealed a significant reduction in total and fecal coliforms, as well as fecal streptococci, indicating the efficacy of the GAC/adsorption filtration system.</p></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"78 18","pages":"9473 - 9483"},"PeriodicalIF":2.2,"publicationDate":"2024-10-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142737291","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Although there are a good number of reviews on pollutants uptake under batch conditions and related operational factors affecting the process, reviews on pollutants uptake under column conditions are relatively few. Hence, the importance of this review comes as it evaluated the performance of many adsorbents under continuous flow conditions, which is considered more practical than batch process. Based on this aim, many synthetic and non-conventional adsorbents were examined which utilized for dyes uptake under batch and continuous flow conditions. It is necessary to assess the performance of the examined adsorbents using both processes to determine the most appropriate one, taking into account the high production cost of synthetic adsorbents. The performance of sixty nine adsorbents for removing different classes of dyes using batch and column type processes are examined in this review. The results are collected under the following criteria: (a) The adsorbent should have maximum uptake capacity higher than 100 mg g⁻¹; (b) Column saturation capacity, operational factors and service time for dye uptake are reported; (c) Adsorbent recycling under dynamic conditions is reported. Based on the earlier criteria a screening guide was proposed for the most efficient dye adsorbent under column conditions: (a) column saturation capacity &gt; 184 mg g⁻¹; (b) column service time &lt; 10 h; (c) the adsorbent should be used up to 5 cycles after regeneration with a green solvent. The most efficient synthetic adsorbent is vinylpyridine-methacrylic acid cryogel toward Basic Blue 9 with column capacity 388 mg g⁻¹, service time 0.8 h and used for 4 cycles with 100% efficiency. For non-conventional adsorbents, modified-chitosan is outstanding toward Basic Blue 9 with column capacity 379 mg g⁻¹, service time 3.4 h and used for 5 cycles with a final efficiency 93%.</p><h3>Graphical Abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"78 17","pages":"8919 - 8939"},"PeriodicalIF":2.2,"publicationDate":"2024-10-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142736811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Favipiravir (6-fluoro-3-hydroxypyrazine-2-carboxamide) is an important selective antiviral against RNA-based viruses, like SARS‐CoV‐2 virus causing COVID-19 disease, and has recently attracted considerable interest. The behavior of Favipiravir in various solvents including water, methanol, ethanol, isopropanol, methyl tert-butyl ether (MTBE), and dimethyl sulfoxide (DMSO) was investigated. A novel iron (III) complex compound derived from FAV as the ligand was synthesized. Subsequently, the newly synthesized complex was subjected to various analytical and spectroscopic techniques, including UV and infrared spectroscopy, mass spectrometry, stoichiometry analysis using the molar ratio method, and thermogravimetric analysis (TG–DTA). It was observed that the keto/enolic equilibrium of favipiravir is influenced by the choice of diluent, with the enol tautomer being the predominant form. Further analysis revealed that the isolated metal complex exhibits a tetrahedral geometry. The complexation reaction is more favorable in a protic medium than in an aprotic one, primarily due to the easier deprotonation in protic environments. Additionally, the molecular structures of the free ligand and its metal complex compound were optimized using density functional theory (DFT) simulations. This study offers valuable insights into the quantum chemical properties related to the structure. The simulation indicates significant chemical stability and a pronounced electrophilic character of the iron complex. Overall, these findings contribute to a deeper understanding of the interaction dynamics and stability of favipiravir's metal complexes.</p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"78 18","pages":"9461 - 9472"},"PeriodicalIF":2.2,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142737076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, curcumin’s clinical effectiveness is significantly limited by its hydrophobic nature, leading to poor bioavailability. This study aims to enhance the solubility and bioavailability of curcumin through the development of liquisolid compact dispersion formulations. To address curcumin’s limited water solubility (3.12 mg/l at 25 °C) and high oil–water partition coefficient (<span>(text{log}Kow=3.29)</span>), we employed a central composite design (CCD) to optimize liquisolid compact dispersion formulations. The optimization focused on the tablet’s physical properties, such as hardness, disintegration time, and dissolution rate at 30 min. Critical formulation components included Tween 80 as the liquid vehicle and Aerosil 200 as the coating material, serving as independent variables in the optimization process. The optimized formulation, containing 30 mg of Tween 80 and 75 mg of Aerosil 200, significantly improved curcumin’s dissolution rate. Experimental results confirmed the formulation’s effectiveness, with a marked reduction in the time to dissolve 63.2% of the drug to 165 min, compared to 300 min for conventional formulations. Differential scanning calorimetry and Fourier-transform infrared spectra indicated a transformation of curcumin into a non-crystalline state and the formation of hydrogen bonds with Tween 80, contributing to enhanced solubility. This study successfully demonstrates a viable strategy to enhance the bioavailability of curcumin through liquisolid compact dispersion formulations. By addressing the solubility challenges of curcumin, this technique presents a significant advancement in improving the clinical applicability of BCS class II and IV drugs, potentially benefiting a wide range of therapeutic applications.</p><h3>Graphical abstract</h3><div><figure><div><div><picture><source><img></source></picture></div><div><p>Graphical representation of optimizing curcumin liquisolid formulation\u0000using central composite design (CCD) methodology</p></div></div></figure></div></div>","PeriodicalId":513,"journal":{"name":"Chemical Papers","volume":"78 17","pages":"9257 - 9271"},"PeriodicalIF":2.2,"publicationDate":"2024-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s11696-024-03741-7.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142737072","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study shows that chemically functionalizing the surface of charcoal with APTES (3-Aminopropyltriethoxysilane) improves adsorption capabilities. Various characterization techniques, such as FTIR, FESEM, TGA, and BET studies, were used to evaluate the efficiency of FTCC. The results showed a considerable improvement in surface qualities that are favourable for adsorption. BET evaluations indicate that functionalized carbon has a high surface area of 1.45766 m².g⁻¹ and a pore volume of 0.534772 cm³.g⁻¹. Adsorption data fit well with Langmuir model and follow pseudo-second-order kinetics. Thermodynamic parameters reveal the endothermic adsorption of Congo red dye and exothermic adsorption of Cr (VI) metal ion. The batch adsorption experiments revealed that FTCC was capable of removing various dyes and metal ions from aqueous solution, with adsorption capacity 65.22 mg/g for Congo red and 56.61 mg/g for Cr (VI). The FTCC showed good reusability potential up to 6th cycle. Additionally, tests with water samples containing contaminants have been conducted to demonstrate the best adsorbent quality of FTCC.
