Abstract

This study investigates the efficacy of activated carbon derived from coconut shells for the removal of Triclosan (TCS) from aqueous solutions. Experimental results demonstrate the impressive efficiency of coconut shell-derived activated carbon in eliminating TCS from water. Statistical analysis underscores the significant role of agitation in enhancing adsorption efficiency, with increased agitation leading to higher contaminant removal rates. Equilibrium is rapidly achieved, with removal efficiencies exceeding 85 %. Kinetic analysis reveals rapid adsorption kinetics, predominantly following the pseudo-second-order model. Additionally, intraparticle diffusion analyses provide insights into TCS diffusion within activated carbon pores, highlighting its dependence on solute concentration. These findings underscore the potential of coconut shell-derived activated carbon as a viable solution for mitigating TCS contamination in water sources, contributing to the development of effective water treatment strategies.
