Fabrication of Magnetic Chitosan-Benzil Biopolymer with Organoclay for Remazol Brilliant Blue R Dye Removal: a Statistical Modeling and Adsorption Mechanism
In this work, a magnetic cross-linked chitosan-benzil/organoclay/Fe3O4 biocomposite (CHI-BZI/OC/Fe3O4) was synthesized as a bio-adsorbent for the removal of remazol brilliant blue R (RBBR) dye from aquatic environment. The adsorption factors i.e., CHI-BZI/OC/Fe3O4 dosage, pH, and time were statistic...

| Summary: | In this work, a magnetic cross-linked chitosan-benzil/organoclay/Fe3O4 biocomposite (CHI-BZI/OC/Fe3O4) was synthesized as a bio-adsorbent for the removal of remazol brilliant blue R (RBBR) dye from aquatic environment. The adsorption factors i.e., CHI-BZI/OC/Fe3O4 dosage, pH, and time were statistically optimized using the Box-Behnken design (BBD). The highest RBBR removal efficiency of 90.9% was achieved at a CHI-BZI/OC/Fe3O4 dosage of 0.1 g/100 mL, initial solution pH of 4.0, and contact time of 20 min. The RBBR adsorption onto the CHI-BZI/OC/Fe3O4 matched the pseudo-second-order kinetic (PSO). Moreover, equilibrium study was conducted and the best fit to the adsoption expsrimantal data was described by Langmuir isotherm model. The adsorption capacity of CHI-BZI/OC/Fe3O4 for RBBR was determined to be 102.9 mg/g. This work contributes to the advancement of environmentally friendly and sustainable methods for treating dye-contaminated water, showcasing the potential of biocomposite materials as effective adsorbents in the field of water purification. |
