| 摘 要： | 重金属的环境行为与其在沉积物上的吸附状况密切相关,沉水植物对沉积物的重金属吸附性能有何影响值得关注.以武汉南湖沉积物为研究对象,对种植沉水植物菹草后沉积物的锌吸附性能变化开展研究,并将沉积物进行逐级分离,分析不同级的沉积物对锌吸附特性的作用.结果表明,Langmuir和Freundlich吸附等温式均能拟合沉积物对锌的... |

| Abstract: | Environmental impact of metals depends on its sorption ability,and role of submerged plant on the adsorption of heavy metals on sediments is of great importance.Zinc adsorption on natural sediment of Lake Nanhu in Wuhan was studied,and effect of Potamogeton crispus on the adsorption of sediments was investigated.The adsorption characteristics of different components in sediments were also discussed in order to understand the adsorption of heavy metals better.It showed that both Langmuir model and Freundlich... |
