Abstract :
This is a study on the decontamination function of two kinds of aquatic plants towards Pb2+, cress and acorus. The results show: both cress and acorus have the ability of removing heavy metal Pb2+, while acorus shows higher decontamination ability, up to 91%. Acorus shows higher accumulation rate of Pb2+ compared to cress and its underground (root) accumulation rate is significantly higher than that on the ground(Stems and leaves); with the Pb2+ concentration of 250 mg/L, the underground accumulation rate is up to 1542.97 mg/kg and that on the ground was 943.61 mg/kg.
