Abstract

Batch studies were carried out to investigate the removal of organic acids by adsorption on fly ash impregnated with hydroxides of Al, Cd, Cu, Fe and Ni. The percentage removals of cinnamic acid, indole-3-acetic acid, β-napthaleneacetic acid, β-naphthoxyacetic acid, oxalic acid and trichloroacetic acid from water were 75%, 63·63%, 100%, 95·25%, 85·71% and 78·26%, respectively. The adsorption data recorded follow the Freundlich adsorption isotherm.
