| Popis: | Sargassum seaweed biomass is capable of selectively removing Cu2+ from water containing Fe2+ in the pH range of pH (3-5). The seaweed can bind up to a maximum of 80 mg of Cu per g of biomass (dry weight by ion exchange. Copper bound to the biosorbent can be desorbed by an acidic wash and the biosorbent can be reused. A flow-through biosorption column packed with Sargassum biomass was used to continuously remove Cu2+ from an aqueous feed. The effect of the presence of Fe2+ in water on the equilibrium uptake of Cu2+ by Sargassum was examined at pH 3.7. The potential for the biosorption process using Sargassum biomass to treat AMD treatment systems was discussed. Total capital and operating costs associated with the biosorption process were outlined. |
