| 摘 要： | 通过对南沙群岛海区表层沉积物与铜离子交换吸附作用的实验研究发现:(1)铜离子在海水条件下与沉积物的交换吸附为一价阳离子交换;(2)不同站位的沉积物对铜离子的交换吸附能力不同;(3)铜离子在沉积物上的吸着行为存在着分级离子/配位子交换反应。

| Abstract: | Exchange adsorption properties of the surficial sediments for Cu 2 in the Nansha Islands sea area were studied. The results are as follows: (1) Exchange adsorption of the sediments for Cu 2 at each station in the Nansha Islands seaNansha Islands sea area is exchange reaction of cation. (2) Exchange adsorption abilities of the sediments for Cu 2 vary greatly with different stations. (3) The exchange adsorption isotherms of the surficial sediments for Cu 2 in the Nansha Islands sea area are stepwise, demonstrating that there exists stepwise ion/coordination particle exchange reaction between Cu 2 and the sediments. |
