| 摘 要： | 于1990年10月 - 1992年7月在室内条件下测定黄河中游乌拉特前旗、包头黄河大桥及清水河地段水体中天然配体与铜、铅、锌、镉反应的络会容量（C?C），计算总条件稳定常数（K）和络合容量指数（I）。实验证明：乌拉特前旗水体中络合客量最大，包头和清水河相近。络合容量顺序为：Cu＞Zn＞Cd＞Pb，和可溶性有机碳及碳酸盐分析结果一致。总条件稳定常数为：KPbL最大，KCuL，KZnL，KCdL相近。和长江水做了比较。络合容量指数在IgK相近情况下，随络合容量增大而增大。

| Abstract: | Anode stripping voltametry used in determing the conditional stability constants and complexation capacity indexes of heavy metals (Cu, Pb, Zn, Cd) in the middle reaches of the Huanghe River in Nei Menggu showed high complexation capacity values at Wulate similar to those at Baotou Bridge and Qingshui river, that the complexation capacity sequence (Cu > Zn > Cd >Pb) concords with results of analysis on DOC and carbonate; that the stability constants (KPbL, maximum, KCuL,KZnL, KCdL, are similar; and that when lgK are similar, the greater the complexation capacity, the greater the complexation capacity index. |
