Abstract:
The biosorption of copper, cobalt and nickel by marine brown alga Sargassum sp. were investigated in a fixed-bed column (temperature=30°C ; different pH). Langmuir and Freundlich sorption models were used to represent the equilibrium data. The maximum Cu2+ uptake was obtained at pH 4 and the optimum Co2+ and Ni2+ uptake were at pH 7. Different dosage of biosorbent did not have an effect on the results, but the 3.5 and 5 g of biosorbent were shown higher uptake. The metal removal rates were rapid, with about 80% of the total adsorption tacking place within 40 min.
