Heavy metal ions such as Ag + , Pb 2+ , and Ru 3+ in aqueous solution are adsorbed onto the aquatic plant Azolla filiculoides followed by conversion to the corresponding metallic nanoparticles by the polyol reaction carried out in a microwave oven. The combined process offers a promising approach for the removal of heavy metals from wastewater using low-cost and environmentally friendly sorbents, and the recycling of adsorbed metals into marketable products. -(CHEFETZ, B.; SOMINSKI, L.; PINCHAS, M.; GINSBURG, T.; ELMACHLIY, S.; TEL-OR, E.; GEDANKEN*, A.; J.

We adsorb heavy metal ions such as Ag(+), Pb(2+), and Ru(3+) onto an aquatic plant and convert the adsorbed ions to the corresponding nanometallic particles by the polyol reaction carried out in a microwave oven.
