研究了在黄河水中溶液 p H值对 Cu( )、Zn( )和 Cd( )分别与转化沙和未转化沙相互作用的离子交换率 E( % )的影响 ,并研究了当甘氨酸存在时对上述相互作用的离子交换百分率的改变 .结果表明 :当沉积物分别为转化沙和未转化沙时 ,其对重金属的吸附作用的影响是不同的 ,且实验结果与理论推测和实际是一致的 ;甘氨酸的存在对不同金属离子分别与转化沙和未转化沙相互作用的离子交换率 E( % ) -p H曲线的影响各不相同 The effect of solution pH on the ion exchange rate E (%) of Cu (superscript +), Zn () and Cd (superscript p) in the Yellow River water was investigated. The effect of glycine on The results show that the adsorption of heavy metals on the sediments is different when the sediments are converted into litter and unconverted sands respectively, and the experimental results are in agreement with the theoretical and practical ones. The effect of glycine on the ion exchange rate E (%) -p H curves for different metal ions interacting with the converter sand and unconverted sand, respectively, varies
