Study on Enrichment of Heavy Metal Pb~(2+) in Water by Alternanthera Philoxeroides

Luo Tian-xiong

Abstract

The results of study on enrichment of heavy metal Pb2+ in water show that the water can be purified by Alternanthera philoxeroides. When heavy metal Pb2+ is 5.0mg/L, pH is 7.0-8.0(optimum is 7.5), temperature is 25℃-30℃(optimum is 25℃), and disposal time is 7 days or more, the existing Pb2+ in the water is less than 0.2mg/L (standard of the state).
