| 摘 要： | 对黄河水中表层沉积物与重金属Cu^2 、Pb^2的交换吸附作用进行了研究。结果表明，在黄河水中Cu^2 、Pb^2 与表层沉积物主要进行一价阳离子交换反应：河水pH是影响Cu^2 、Pb^2 与表层沉积物交换吸附的主要因素。Pb^2 与表层沉积物的交换吸附能力大于Cu^2 ；温度升高有利于Cu^2 、Pb^2 与表层沉积物的交换吸附。

| Abstract: | The interactions of ion exchange adsorption between surface layer sediments and heavy metals Cu 2 ?Pb 2 in the Yellow River were studied. The results showed that the sediments and Cu 2 ?Pb 2 mainly carried out univalent cation exchange reactions in the Yellow River. The pH value of the Yellow River water was the main factor affecting exchange adsorption of Cu 2 ?Pb 2 and surface layer sediments. The exchange adsorption ability of Pb 2 and the surface layer sediments was bigger than that of Cu 2 . The exchange adsorption action of Cu 2 ?Pb 2 and surface layer sediments was promoted as the temperature rose. |
