Abstract
The adsorption of chromium ions from aqueous solution onto activated c harcoal cloth was studied. It was found that under all conditions inve stigated, the amount of chromium adsorbed from chromate(VI) was ten ti mes greater than that from chromic(III) solutions. To account for the quantities adsorbed additional surface processes are proposed. In addi tion to adsorption, chromate ions burrow into and widen the micropores . while chromic ions dehydrate and migrate into micropores.
