Silver Modified Hydrophytes for Heavy Metal Removal from Different Water Resources

Abstract

Phytoremediation of three different aquatic plants powders Lemna minor L., Azolla filiculoides Lam. and Pistia stratiotes L. studied against different heavy metals (HM) and after modifications with interfacial layer synthesized silver nanoparticles. Prepared samples tested for the selective absorbance of chromium, cadmium, lead, and zinc. L. minor and P. stratiotes show selective absorption against lead, while Azolla filiculoides show higher absorption against chromium. Absorption of all heavy metal concentrations was found to be enhanced after interfacial modification with green synthesized silver nanoparticles.
