Effective removal of crystal violet by ligno-cellulosic material and its acid-treated form: characterization, experiments, and modeling Koushik Ghosh, Shraddha Sinha, Nirjhar Bar, Asit Baran Biswas, Sudip Kumar Das International Journal of Phytoremediation, 2026 , PBL > SBL > BL. The thermodynamic parameters reflect disorder, spontaneity, and a heat-absorbing nature. The investigational data have been examined successfully using a genetic algorithm (GA) and multiple polynomial regression (MPR). The adsorbent's performance in actual industrial effluents (including reductions in COD, BOD, TDS, turbidity, and color) demonstrates its economic feasibility compared with commercial activated carbon, thereby enhancing the practical relevance of the study.
Adsorptive removal of Ni(II) using nickel-resistant dead S. cerevisiae AJ208 Jayeeta Banerjee, Nirjhar Bar, Sudip Kumar Das Journal of Dispersion Science and Technology, 2025 Recent trends in environmental pollution urge for immediate resolution of Ni(II) elimination as industrial effluents from wastewater. From that perspective, bioremediation substantiates an effective practice for eliminating Ni(II) using a potential biosorbent. In this study, the Ni(II) elimination efficacy of 5000 mg/L Ni(II) resistant dead S. cerevisiae AJ208 is elaborately explained with physical parameter optimization and established by SEM-EDAX analysis. FTIR study validated that carboxyl, hydroxyl, carbonyl, and amine are accountable for biosorption. Investigational findings fit well in the Langmuir model, representing a single-layered adsorption process. Obtained Langmuir maximum adsorption capability is 201.61 mg/g. The pseudo-second-order model fits well with the experimental data, which signifies chemical adsorption. The experimental data have been analyzed using statistics and a genetic algorithm (GA). Ni(II) resistant dead S. cerevisiae AJ208 could substitute the expensive elimination techniques to decontaminate Ni(II) from industrial wastewater.
Chitosan-nTiO2 Nanocomposite Synthesis and its Adsorptive Removal Capacity for Methylene Blue from its Aqueous Solution: Batch Adsorption Study and Modeling Samanwita Bhattacharya, Nirjhar Bar, Baisali Rajbansi, Sudip Kumar Das Chemistryselect, 2024 The current work used chitosan (CS)‐nTiO2 nanocomposites (CTNCs) prepared with different CS:nTiO2 mass ratios toward the MB dye removal from an aqueous medium in batch method at variable experimental conditions. The stability and competence of the nanocomposites were checked through characterization by SEM, FTIR, XRD, TGA, and BET. The highest removal of MB was 78 % with the adsorbent CS without nTiO2 (CWT), 94.5 % with CS:nTiO2=1 : 1 weight ratio (CTNC1‐1) and 80 % with CS:nTiO2=2 : 1 weight ratio (CTNC2‐1) with 10 mgL−1of MB and 5 gL−1 adsorbent dosages. The experimental observations obeyed the pseudo‐2nd‐order model, and rate‐limiting steps were film diffusions for CWT, CTNC1‐1 and intraparticle diffusion for CTNC2‐1. Monolayer adsorption was established from the isotherm model. Langmuir adsorption capacities for MB were presented as CTNC1‐1 (qL=34.31)>CTNC2‐1 (qL=32.87)>CWT (qL=21.32). The sorption energy, as derived from Dubinin–Radushkevich isotherm model, showed physisorption for all three adsorbents. The scale‐up design is reported. The statistical (R2>0.98) and GA modeling (R2>0.98) successfully predicted the percentage elimination of MB. Thus, CS‐nTiO2 nanocomposites are prepared as novel and environment‐friendly adsorbents for dye removal.
Adsorptive elimination of methylene blue dye from aqueous solution by chitosan-nSiO2 nanocomposite: Adsorption and desorption study, scale-up design, statistical, and genetic algorithm modeling Samanwita Bhattacharya, Nirjhar Bar, Baisali Rajbansi, Sudip Kumar Das Environmental Progress and Sustainable Energy, 2024 Heavy metals and organic dyes in water in concentrations exceeding the tolerable limit are unsafe for aquatic life and humans. Chitosan nanocomposites show a potential adsorption capacity to organic dyes. The present study encompasses the preparation of chitosan‐nSiO2 nanocomposites (CSNC) with different weight ratios of chitosan to nSiO2 and its application in the methylene blue (MB) dye adsorption. The nanocomposites were characterized with the help of SEM, BET, FTIR, XRD, and TGA. The adsorption experimentation was executed in batch mode under varying experimental conditions. Several isotherm and kinetic models were analyzed with the experimental data, and thermodynamic conditions required for adsorption were also determined. Maximum Langmuir adsorption capacities (qL) of the adsorbents for MB varied in the range of 21.32–31.34 mg g−1. The pseudo‐second‐order model was the best‐fitted kinetic model concerning all three adsorbents. The statistical modeling using multiple polynomial regression (MPR) for CWS CSNC1‐1 and CSNC2‐1 yielded the equations with R‐square ranging from 0.984 to 0.996. For GA modeling, it is more than 0.999. So, the efficient employment of statistical modeling, and genetic algorithms has also been achieved.
Methylene blue dye removal by adsorption with coconut coir and acid-treated forms: adsorption-desorption study, MPR and modeling using artificial intelligence Indrajit Ghosh, Nirjhar Bar, Sudip Kumar Das Journal of Dispersion Science and Technology, 2024 A batch study is conducted to remove methylene blue (MB) dye from an aqueous solution using coconut coir and its acid-treated forms. The sulfuric acid-treated coconut coir (SCC), phosphoric acid-treated coconut coir (PCC) and untreated coconut coir (UCC) were prepared. Adsorbents were characterized via BET, SEM, pHPZC, FTIR, and FT-Raman analysis. Adsorbent’s total organic carbon (TOC) and the number of oxygen-containing functional groups like carboxylic, lactonic and phenolic, total acidic, and basic groups were also estimated. FTIR and FT-Raman studies establish functional groups responsible for dye removal. The operating parameters were optimized through experiments. Dye was removed maximally at the lowest temperature, 303K. Langmuir and Temkin isotherm models use linear equations, and the Pseudo-second-order kinetic model uses a nonlinear equation, which fits well. The adsorption capacity of SCC, PCC and UCC adsorbents was 88.18 ± 0.63 mg/g, 92.68 ± 2.74 mg/g and 76.39 ± 0.36 mg/g, respectively, for 303K. Intraparticle diffusion dominated more than film diffusion. Physisorption was estimated by applying the Dubinin-Radushkevich (D-R) isotherm model. Thermodynamic study indicates a spontaneous, favorable, exothermic process. 75% glacial acetic acid and 100% methanol are the best solvents for desorbing dye-loaded adsorbents. Porous coir and non-covalent interactions like hydrogen bonding, van der Waals force and π-π interaction between dye and coir are vital in the dye removal process. The regression equation has been successfully formulated, and the application of a genetic algorithm has predicted the percentage removal of methylene blue dye.
