| Abstract | ||
| A new chitosan-cellulose@agarose composite (CS/CA@AG) was synthesized and thoroughly characterized using FTIR, TGA, XRD, SEM, and BET techniques for efficiently removing oil from wastewater through adsorptive processes. The study investigated at how the adsorption process is affected by a number of variables, such as contact time, pH, initial concentration of oil, dose of adsorbent, agitation rate, and temperature. Kinetic, equilibrium, and thermodynamic models were analyzed. Maximum oil adsorption occurred at pH 8, and for the kinetic data, the pseudo-second-order model provided the best description. The equilibrium data fit to both the Langmuir and Freundlich models, with a maximum adsorption capacity of 7142.86 mg/g. These results indicate that the biocomposite represents a promising, eco-friendly, and economically viable method of oil removal from wastewater. | ||
