摘要
草炭有机质提取物胡敏酸、富里酸、水溶解态有机质的红外光谱研究显示 ,三者的含氧官能团组成相似 ,但基团含量差异较大 .胡敏酸、富里酸、水溶解态有机质与金属离子 (Cu2 +、Cd2 +、Pb2 +、Zn2 + )络合物的红外光谱表明 ,除 -COOH外 ,-OH、C=O、-NH2 等官能团也参与了对金属离子的络合 。
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.
