摘要
对黄河水中表层沉积物与重金属 Cu2 +、Pb2 +的交换吸附作用进行了研究。结果表明 ,在黄河水中 Cu2 + 、Pb2 + 与表层沉积物主要进行一价阳离子交换反应 :河水 p H是影响 Cu2 + 、Pb2 + 与表层沉积物交换吸附的主要因素。 Pb2 + 与表层沉积物的交换吸附能力大于 Cu2 + ;温度升高有利于Cu2 +、Pb2
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.
