Abstract: Through the lab study on Pb2+ in water adsorbed by green algae in fresh water,such as stigeoclonium, cladophora and spirogyra, it opens out the adsorbing relationship between green algae and Pb2+ and the main influence factors. The experiment showed that the green algae in fresh water had a strong adsorption on plumbum, and the adsorptive efficiency would be 40% when pH was 4,the temperature reached 28℃ and the 2 g algae adsorbed the 20 mL liquor which contained Pb2+ of 100 mg/L.

Key words: green algae in fresh water, plumbum, adsorption
