New ideas are presented on the covalent attachment of chelating functionalities to novel, highly hydrophilic sobent material, which can then complex heavy metal ions irreversibly and is targeted toward lead removal. The efficient removal of other heavy metals, such as cadmium, chromium, mercury, zinc, nickel, cobalt, and cooper are anticipated. The covalent attached ligands are expected to be stable towards hydrolysis and pH variations. The capacity of the chemically modified sorbent materials will be evaluated for the above mentioned heavy metal ions in the presence of calcium and magnesium ions and for simulated water samples. The sorbent material and the eluted water samples containing multi-elements before and after sorption will be examined by sensitive analytical methods.
