Abstract

A method of adsorbing manganese from an aqueous solution comprises (a) contacting a solid adsorbent with aqueous alkaline solution, (b) directly contacting the adsorbent resulting from step (a) with the manganese-containing solution, and (c) separating the adsorbent from the solution. Adsorbents may be chitin, chitosan, peanut skins, coconut peat, onion skins, peanut cases and wood chips.
