有机物对黄河水中重金属与沉积物相互作用的影响(英文)

Effect of Organics on the Interaction between Heavy Metals and Sediments in the Yellow River

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

The effects of pH value on the ion exchange radio E (%) of the interaction of Cu(Ⅱ),Zn(Ⅱ) and Cd(Ⅱ) with sediments which include the untransform sand and the transform sand in the Yellow River have been studied.The changes of the ion exchange percentage E (%) of the interaction of both in the presence of the glycine have been presented.The results are that the effects of the transform sand and untransform sand on the adsorption are different,which agree with the reality and the theory inferrer.
