Abstract
In this study, two aquatic macrophytes namely, Azolla pinnata and Lemna minor are floating plants were obtained from Agric. Microbial Dept., Soils, Water and Environment Research Institute (SWERI), Agric. Res. Center (ARC), Giza, Egypt and used to some heavy metal such as Iron, Zinc and lead This study reported the ability of two aquatic plants (A. pinnata and L. minor) to remove Iron, Zinc and lead from aqueous solutions FeSO4.7H2O, ZnSo4.7H2O and C4H6O4Pb.3H2O of four different initial concentrations (0–100 ppm) for 20 days under greenhouse conditions. The results indicated that A. pinnata gave higher growth density than that recorded for L. minor during all the tested incubation periods from zero time up to 20 days. Results obtained in this study showed a maximum removal of Fe, Zn (88.18, 84.63 %) by L. minor at 100ppm initial metal concentration however the maximum removal by A. pinnata at the same concentration was (86.97, 81.14%) after 20 day of incubation. These A. pinnata appeared to be more efficient than L. minor for removing Pb .On the other hand A. pinnata was better than L. minor in biomass for each of the elements used in the experiment during the incubation period.
