Abstract |
|
|
| In this investigation, we discussed the mechanistic analysis of the adsorption process employing chemically modified chitosan, conjugated with zirconium (Ch@Zr), for the removal of fluoride from aqueous solutions. The chitosan was chemically modified through microwave-assisted heating, while zirconium binding was accomplished using conventional chemical techniques to improve its fluoride adsorption efficacy. The adsorption mechanism was elucidated through a series of experimental procedures and analytical techniques, including surface characterization. Various parameters such as adsorbent dosage, pH, temperature, initial fluoride concentration, and contact time were systematically studied to optimize the adsorption process. The findings demonstrate that the modified Chitosan@zirconium exhibits a superior fluoride adsorption capacity, achieving maximum removal efficiency under optimized conditions. The adsorption process was evaluated using isotherm and kinetic models, including Freundlich and Langmuir isotherms, pseudo-second- order kinetics, Elovich model, and Webers intraparticle diffusion model. This mechanistic insight contributes to the remediation of fluoride-contaminated wastewater by providing valuable information for developing effective fluoride removal strategies utilizing modified chitosan.
