摘要：
Different heavy metals can be eliminated by non-living or living biomass. Various aquatic plants species can be applied for the removal of metals. In this research, cadmium, copper, zinc and lead adsorption properties of Lemna minor L. and Eichhornia crassipes (Mart.) Solms were examined. This work was carried in the laboratory to ascertain the efficiency of aquatic plants Eichhornia crassipes and Lemna minor on the removal of various metals. Two plants Lemna minor and Eichhornia crassipes were obtained in a dehydrated powder type. The adsorption procedure of various metals was investigated under different pH ranges, metal ion concentration and reaction times as well as noticed the chemical composition of these plants. The results indicated that both submerged aquatic plant powders can be effectively used for heavy metal elimination under various factors. The FTIR spectra analysis showed a various functional groups in both aquatic plants, they accelerated the adsorption process.
