| Abstract: | The infrared spectra of humic acid (HA), fulvic acid(FA) and water soluble organic matter (WSOM) extracted from peat indicated that their oxygen containing functional groups were similar. But the contents of functional groups were obviously different. An infrared spectroscopic investigation of the complexes of four metal ions with HA, FA, WSOM demonstrated the participation of -OH, C=O and -NH 2 groups in addition to -COOH in binding of heavy metal cations. But which metal ion had the biggest complexing tendency with HA, FA or WSOM could not be clearly revealed by the IR method. |
