• ions from liquids, aqueous model solutions were prepared. The solutions and particles were analyzed by IR spectroscopy, EDX and AAS measurements after the tests. For this purpose, approx. 8 mg of surface-modified nanoparticles were added to a 0.1 M aqueous solution of Pb2+, Cu2+ and Cd2+. This mixture

• end, the nanoparticles were washed and dried at RT to powder form. The functionalization of the nanoparticles with glutaraldehyde starts with washing and mixing by sonication of surface-modified nanoparticles in Tris-HCl solution (pH 7.4). Then, a 5% solution of glutaraldehyde was added and the
