| 摘 要： | 采用批量法对温州景山森林公园5种不同城市土壤对Pb和Zn的吸附热力学行为进行了研究。结果表明，吸附等温线符合Freundlich等温式和Temkin等温式，相关系数都在0．85以上，5种土壤对Ph的吸附强度由高到低的次序为C，E，B，A，D，对Zn的吸附强度由高到低的次序为C，E，D，B，A。

| Abstract: | Sorption thermodynamic of Pb,Zn was studied by the batch method on five different soils of Jingshan Forest Park in Wenzhou,it was shown that Pb and Zn of the adsorption isotherms can be fitted to Freundlich and Temkin adsorption equation with the coefficients larger than 0.85.The order of Pb adsorption intensity is C,E,B,A,D and for the Zn is C,E,D,B,A in the five kind of soils. |
