摘要
该文研究了铜、锌、铅和镉等四种重金属在淀山湖沉积物上的吸附特性,研究发现淀山湖沉积物对Cu、Zn、Pb和Cd的吸附符合Langmuir模型.沉积物对重金属饱和吸附量和重金属在沉积物-水两相中的分配系数的大小顺序均为Zn>Cu>Pb>Cd,表明锌和铜比铅和镉更容易迁移入沉积物.
The adsorption characteristics of Cu, Zn, Pb and Cd on Dianshan Lake sediments are studied. The results of isothermal adsorption show that adsorption of these heavy metals on Dianshan Lake sediments accords with the Langmuir model. The order of both the amount of saturated adsorption and the partition coefficients between sediments and water for heavy metals are Zn>Cu>Pb>Cd. Therefore Zn and Cu transport into sediments more easily than Pb and Cd.
