The effects of two different organic acids, citric and oxalic, on the capacity of chitosan flakes to remove heavy metal ions, namely Zn2+, Cu2+, Cd2+, and Pb2+ from aqueous solutions were studied. A significant reduction in chitosan's adsorption capacity for heavy metal ions was observed in response to both organic acids, particularly when used at concentrations higher than 10(-2)M. The magnitude of reduction in response to citric acid was slightly greater as compared to oxalic acid.
