摘　　要：本文研究了两种氨基酸对黄河水中铅( II)与固体粒子相互作用的离子交换率E( % )—p H关系曲线的影响,结果表明:1随着p H值增大有利于“固体粒子+有机物+金属”络合物的形成,且使离子交换率提高。2体系中加入氨基酸,离子交换率提高。The effect of tryptophan and Proline on the curves of ion exchange ratio E%-pH in the interaction between Pb（ Ⅱ ） with solids in the Yellow River was studied ,There are major results. ？ It is advantageous to form complex compound og ＂ solids ＋ organic , compound ＋ metal＂ with pH value gradually rise （1-10） ,and ion exchange ratio enhancing;! As compared to the control experiment , the ion exchange ratio enhancing as the put in amino acid , and enhancing of extent： Proline 〉 Tryptophan.
