摘要
研究了黄河水中胱氨酸对铅（Ⅱ）与悬浮粒子相互作用的离子交换率E（％）—pH关系曲线的影响。结果表明：（1）2．0μmol·L-1的胱氨酸降低了离子交换率E（％）；（2）与未加有机物相比“S型曲线”左移0．95个pH单位；（3）随着胱氨酸浓度的增加，离子交换率提高。
The effect of cystine on the curves of ion exchange ratio E(%)—pH in the interactiono between Pb(Ⅱ) and suspended particles in the Yellow River was studied. The results show that: (1) 2mol. L-1of cystine can decrease the ion exchange ratio; (2) As compared with the control experiment the S-shaped curve of cystine moves in the direction of lower pH value by 0.95 units; (3) the ion exchange ratio enhances as the concentration of the cystine rises.
