摘要
研究了天门冬氨酸对黄河水中表层沉积物与铅 (Ⅱ )相互作用的离子交换率—pH关系曲线的影响 .结果表明 :天门冬氨酸浓度增加 ,离子交换率增大 ;交换剂在转化沙时的离子交换率比未转化沙大 .
The effect of Asparticacid on the curves of ion exchange ratio E% ～pH in the interaction between sediment of surface Lager and Pb(Ⅱ) in the Yellow River was studied.There are major results: the ion exchange ratio increases as the concentration of Asparticacid rises,the ion exchange ration of lead is bigger when the exchange reagent is the transformed sand than it is the non transfromed sand.
