The adsorption of mercury(I1) acetate from aqueous solution onto an activated charcoal cloth (ACC) has been studied using shaking and flow-through techniques. It was found that the adsorption capacities of the ACC shaken in mercury(I1) acetate solution could reach 2 x 10e3 mol g-' at pH 5.5. The flo

β¦ Synopsis
The adsorption of chromium ions from aqueous solution onto activated charcoal cloth was studied. It was found that under all conditions investigated, the amount of chromium adsorbed from chromate was ten times greater than that from chromic(lI1) solutions. To account for the quantities adsorbed additional surface processes are proposed. In addition to adsorption, chromate ions burrow into and widen the micropores, while chromic ions dehydrate and migrate into micropores.
