Macrophytes biomass including Spirodela intermedia, Lemna minor, and Pistia
stratiotes was reported in the literature and the mechanism of simultaneous metal removal ([Cd.sup.2+], [Ni.sup.2+], [Cu.sup.2+], [Zn.sup.2+], and [Pb.sup.2+]) by them was investigated [20].
Summary: The non-polar compounds of the Pistia
stratiotes were extracted using n-hexane as solvent.

Few specimens of the macrophytes Lemna sp, Pistia
stratiotes and Alternenthera philoxeroides collected from the irrigation canals were added to the tubs to simulate natural conditions.
