中文摘要：

正面的亲密关系层析被用于描绘银的绑定的机制，沉积微粒从安大略湖，收集了加拿大。结果证明为在微粒的 Ag+ 有一个主要有约束力的地点。有约束力的能力从 6.06 ～ 1.01 ?????? 溜 ??  ??????? 吗？？

英文摘要：

Frontal affinity chromatography was applied to characterizing the mechanism of binding of silver with sediment particulates collected from Lake Ontario, Canada. The results showed that there was one major binding site for Ag^＋ in the particulates. The binding capacity ranges from 6.06 to 1.01 μ·mol·g-^1, and the binding constant （lgK） from 6.23 to 7.43 M^-1 in 0.005 M ion strength at pH=3-7. The binding capacity and affinity constant were found to be pH-dependent. It is suggested that the particulate surface site where silver was bound was the anionic base. This study would be helpful for better understanding of the fundamental environmental chemistry of silver in sediments.
