Adsorption of Fe(III) from aqueous solution by acanthaceae activated carbon
In this study, a series of batch laboratory experiments were conducted in order to investigate the feasibility of Acantheace activated carbon for the removal of iron from aqueous solution by adsorption process. Batch experiments were performed as function of process parameters like contact time, initial concentration of iron, temperature, carbon dose and effect of pH. All batch experiments were carried out at a constant temperature of 30°C using wrist action shaker that operated with a speed of 120 rpm. The single component equilibrium data was analyzed using Langmuir, Freundlich isotherms. The kinetic process of iron adsorption on Acantheace activated carbon was described by AAC applying pseudo second order rate equations, Elovich and intra-particle diffusion models. The AAC investigated in this study exhibited a high potential for the removal of iron from aqueous solution.
