Description:
New ideas are presented on the covalent attachment of chelafing functionalities to a common, inexpensive sorbent material, which can then complex heavy metal ions irre- versibly. The efficient removal of lead, cadmium, chro- mium mercury, zinc, nickel, cobalt, iron, and copper is anticipated. The covalently attached ligands are expected to be stable towards hydrolysis and pH variations. The capac- ity 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 before and after sorp- tion will be examined by neutron activation analysis, and the eluted water will be analyzed by Inductively Coupled Plasma Mass Spectrometry.Supplemental Keywords:
