This innovative approach addresses waste management challenges while offering a cost-effective and sustainable solution for water treatment. The research evaluates the effectiveness of BPD in a batch system and optimizes the process using Response Surface Methodology (RSM). Detailed characterization of the adsorbent was performed using advanced techniques including scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), Point of Zero Charge (pHzpc), Brunauer–Emmett–Teller (BET) surface area analysis, and Fourier Transform-Infrared Spectroscopy (FTIR). Isotherm analysis revealed that the Langmuir model provided an excellent fit (R² = 0.994), with a maximum adsorption capacity of 47.619 mg/g for BPD. Kinetic studies indicated that the pseudo-second-order model was most appropriate (R² = 0.969). Thermodynamic analysis showed that nitrate removal is more favorable at lower temperatures, with an increase in free energy at 313 K and a negative enthalpy value (-28.873 kJ/mol). Optimization via RSM identified optimal conditions: initial nitrate concentration of 83.92 mg/L, pH 3.57, contact time of 38.37 minutes, and temperature of 42.29 ℃, achieving a desirability score of 1.0. Furthermore, Density Functional Theory (DFT) analysis elucidated the adsorption mechanism, highlighting the predominance of C-O interactions in the ligand exchange process, with an electrophilicity index (ω) of −1.331 eV.

Green products, particularly bio-derived fuels and chemicals, emerge as powerful solutions for mitigating greenhouse gas (GHG) emissions, combating global warming, and satisfying the energy needs of humanity. Today, concerted efforts are underway to produce petroleum-derived liquid fuels like butanol and diesel from renewable sources (e.g., LB). Despite LB currently serving as a significant energy source for many nations, the widespread adoption of technologies that can advance LB beyond burning for energy generation remains limited. Moreover, utilization of LB-derived sugars for fermentative production of fuels and chemicals is plagued with poor performance, largely due to the generation of lignocellulose-derived microbial inhibitory compounds (LDMICs) during pretreatment and hydrolysis of LB into sugars. This review provides an overview of global LB production and utilization, providing insights into both its current status and potential future directions. Specifically, the review paper focuses on various pretreatment options for the conversion of LB into sugars, delving into the mechanistic effects and strategies to abate the generation of LDMICs during pretreatment. Additionally, it explores innovative renewable strategies aimed at optimizing the utilization of second-generation feedstocks in biodiesel synthesis, thereby highlighting promising mitigating strategies toward achieving zero emissions.</p></div>","PeriodicalId":101197,"journal":{"name":"Sustainable Chemistry One World","volume":"2 ","pages":"Article 100007"},"PeriodicalIF":0.0,"publicationDate":"2024-05-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140950644","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The adsorption efficiency of TARH was improved by pre-treating rice husk biochar using tartaric acid (organic acid), which was confirmed by FT-IR measurement, indicating the presence of carboxylic acids, hydroxyl groups, and amine surface functional groups. The study optimized fluoride batch adsorption experiments by considering the parameters affecting adsorption, including pH, contact time, initial concentration, and adsorbent dosage using the Central Composite Design (CCD) from Response Surface Methodology (RSM). Maximum fluoride adsorption of 74.73% was attained by TARH under ideal circumstances (an initial fluoride concentration of 32 mg/L, a pH of 7, 0.25 g/100 mL of adsorbent dosage, and 180 minutes contact duration).

Three-dimensional response surface plots were visualized to analyse the effects of control parameters on %adsorption, and statistical analysis supported the validity of the CCD model.

The adsorption exhibited monolayer adsorption according to the Langmuir isotherm model and a pseudo-second-order rate-limiting phase due to chemisorption.
