Oximes constituted an
important ligand group of coordination chemistry, have amphoteric property and
compose of azomethine (>C=N-) and (-OH) groups. The complexes of transition
metals with oxime ligands have been extensively studied in recent years. In
this study we investigate the removal of Pb2+, Fe3+ and
Zn2+ from wastewater using dimethylglyoxime (oxime) ligand. In these
studies, dimethylglyoxime ligand formed complexes by reaction with high
concentrations of iron, lead and zinc ions at physiological pH and room
temperature. The obtained complexes are a water-soluble even in high
concentration. The resulting complexes were analyzed by Fourier-transform
infrared spectroscopy (FT-IR) and
elemental analysis. The remaining metals were determined by Inductively Coupled
Plasma-Mass Spectrometer (ICP-MS). According to ICP-MS results, concentrations
of metals were dropped to 5 ppm for Pb, 4 ppm for Hg and 2.5 ppm for Fe from 50
ppm. The FT-IR spectrum showed that the peaks of ligand shifted and new peaks
of metal-ligand formed after complexation. These results showed that Pb2+,
Fe3+ and Zn2+ ions in certain concentration known in waste
water and formed a complexes with dimethylglyoxime ligand.
