摘要
研究了黄河水中甘氨酸对铅(Ⅱ)与表层沉积物相互作用的离子交换率E%—pH的影响.实验结果表明:①在2×7.73×10-3mmol·L-1甘氨酸存在下,离子交换率降低;②随着甘氨酸浓度的增加,S型曲线与未加甘氨酸相比,先左后右移动;③甘氨酸存在下,转型表层沉积物比自干表层沉积物离子交换率高.
A study of effect of Glycine in the Yellow River interacts between Pb(Ⅱ) and surface layer sediments on E%-pH relationship was made.The results are obtained: ① E% drops in the condition of exist of 2×7.73×10-3mmol·L-1 Glycine. ② With concentration of Glycine increasing,and compared with no Glycine,S mould curve moves in the left previously and in the right later. ③ When there is Glycine in the water,E% of changing mould surface layer sediments is higher than that of drying surface layer sediments by itself.
