Abstract
Influence of pH and ionic strength upon the sorption of Cd2+ and Pb2+ ions by humic acids was studied. Maximal sorption capacity of humic acids towards Cd2+ and Pb2+ proved to be 0.85 and 0.90 mmol/g, respectively. Modification of humic acids by the chitosan natural polymer helps to stabilize the complex, as well as to raise sorption capacity as compared to the humic acids up to almost 50%.
