| 摘 要： | 以表层沉积物中的粘土为研究对象,利用选择性萃取分离-吸附-加和模型方法考察了粘土及主要组分(铁锰氧化物、有机质和粘土矿物)吸附Cu,Zn的热力学特性。结果表明粘土吸附Cu,Zn的能力略高于表层沉积物吸附Cu,Zn的能力,且粘土中铁锰氧化物对Cu,Zn吸附的相对贡献最大,有机质次之,粘土矿物最小,与表层沉积物中各组分吸附Cu,Zn的规律一致,说明铁锰氧化物控制水环境中痕量重金属的作用不容忽视。 |

| Abstract: | Selective chemical extraction-adsorption-additivity model was employed to analyze thermodynamic characteristics of Cu and Zn on the clay and its main components(Fe/Mn oxides,organic materials and clay minerals) in surficial sediments.The results show that the adsorption ability of clay towards Cu and Zn is much stronger than those of surficial sediments,and the most contribution was attributed to Fe oxides in the clay for Cu and Zn adsorption,next to OMs,and with the least from clay minerals.The resulted in... |
