Abstract
The feasibility of using oyster shell powder for the removal of Cu2+ from aqueous solutions was investigated employing an adsorption technique. Oyster shell powder with different size was prepared. Its adsorption property to copper ions was studied. It was found that in an aqueous medium of pH 7.0, the adsorptive capacity of copper ions increased gradually with the increase of adsorption time, the addition amount of oyster shell powder and decrease of particle size. Compared with other treatment methods, this method has advantages of simple process, low cost, good treatment effect, it has a good application prospect.
