It was necessary, however, to investigate the optimization of liquid–liquid extraction (LLE) in this study because of the technical difficulties encountered during the recovery of VFAs. For this reason, the organic solvents diethyl ether, trioctylamine, and toluene were investigated as LLE solvents to extract VFAs from Baker’s yeast industry effluent, which contains high levels of organic matter. An optimal pH value of 3 was determined by a pH scan performed between pH 2.5 and pH 7.5. Principal component analysis (PCA) was used to determine the effects of organic solvents and pH on extraction efficiency. The extraction efficiency was evaluated using the optimal pH and multi-stage extraction experiments. In a three-stage extraction, diethyl ether recovered 82% of the VFAs, making it a promising organic solvent for extracting VFAs from anaerobic fermentation broth. PCA revealed that an opposite correlation between VFA recovery and pH for each organic solvent. Based on the results of the cost analysis, it was determined that the costs of recovering VFAs were reduced by 90% per kilogram.","PeriodicalId":363,"journal":{"name":"Journal of Industrial and Engineering Chemistry","volume":"3 1","pages":""},"PeriodicalIF":6.1,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141568903","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a hybrid system CuFeZnO − layer double oxide (LDO)/PMS/US designed for the degradation of ofloxacin (OFC) and total organic carbon (TOC) from drugs and pharmaceuticals wastewater. Catalyst 0.4CFZ-LDO exhibited a remarkable catalytic activity for OFC (98.76 %, 0.0703 min) and TOC (76.97 %, 0.0259 min) removal, with synergistic index value (OFC, 3.45) and (TOC, 1.69) under the optimum conditions. The quenching experimental study reveals that sulfate radical (SO) was dominant reactive oxygen species (ROS) for OFC and TOC removal. Density functional theory (DFT) demonstrates that strong attacking sites on the OFC structure were C14, C15 and C23 due to high concentration of Fukui index. Based on the as quantitative structure–activity relationship (QSAR) prediction model system 0.4CFZ-LDO/PMS/US potentially reduced the bio-toxicity (acute toxicity, mutagenicity, bioaccumulation factor) after treatment. Furthermore, catalyst 0.4CFZ-LDO demonstrated remarkable stability with minor leaching of metal ions. Critical contribution of Fe/Fe and Cu/Cu surface catalyzed-redox cycle was evaluated with the help of X-ray photoelectron spectroscopy (XPS) analysis. Furthermore, six potential routes of OFC degradation were proposed based on the DFT study, and intermediates were identified by GC–MS analysis.

The results revealed that the polysaccharide ratio significantly influenced the hydrogel swelling capacity of hydrogel, and a 1:1 ratio of agar to κ-carrageenan achieved the highest swelling degree of 1386 %. Addition of KCl, as a cross-linker, increased swelling capacity to 1713 %. Furthermore, surfactant concentration also influenced swelling behavior, and higher concentrations resulted in an increase in hydrophilicity and swelling. Hydrogel swelling performance varied across physiological fluids, with the highest and lowest swellings observed in deionized water (DIW) and simulated wound fluid (SWF), respectively. The swelling process in DIW and phosphate buffered saline (PBS) exhibited second-order kinetics, whereas non-Fickian diffusion mechanisms were observed in SWF.

Characterisation revealed that CNTs-S-O-Mn contained hydroxyl, sulphonate groups, MnO and MnO. At 298 K, 15.362 mg·L initial concentration of lead ions, and 18.4 % phosphoric acid concentration, the adsorption capacity of the composites for lead ions was 38.65 mg·g, which was higher than that of the unmodified CNTs, 8.04 mg·g. The adsorption kinetic data at 298 K conformed to the quasi-second-order kinetic equation, R = 0.997; 298, adsorption isotherms at 308 and 318 K conformed to the Langmuir equation, R = 0.990–––0.991. The adsorption capacity increased with decreasing phosphoric acid concentration. In this system, the adsorption is affected by a certain concentration of lead ions. Adsorption occurs via chemisorption and is exothermic. Sulfonic acid groups and hydroxyl groups on manganese oxides play an important role in the adsorption of Pb (II) through surface complexation with Pb (II).

Herein, the eco-friendly, low cost and bio-based basil seed (BS) hydrogel is combined with activated carbon (AC) to synthesize activated carbon merged with basil seed hydrogel (AC-BS) composite material. Due to the photothermal property of the AC, the AC-BS composite was used to design an interfacial solar steam generator (ISSG) for water purification. The AC absorbs the sunlight and converts it to the required heat needed for water evaporation and the superhydrophilic BS hydrogel supplies water to the surface causing the high salt rejection ability of the system, in addition, it decreases the required energy for evaporation. The AC-BS is characterized using characterization methods such as EDX and FESEM. The two-dimensional (2D) AC-BS system containing a cotton fiber used to transfer water from the bulk to the surface, a layer of styrofoam as a heat insulator and AC-BS on the surface shows evaporation rate of 1.93 kg mh. The three-dimensional (3D) AC-BS, designed to solve the solar irradiation angle fluctuation problem during a day and seasons, shows an evaporation rate of 2.70 kg mh and an efficiency of about 91 % under 1 sun illumination. The ability of the AC-BS system for saline water desalination and waste water-contaminated dyes as a pollutant treatment is highly acceptable.
