摘要： 研究了菜园土（青紫泥）对铅的吸附、解吸特性，结果表明:铅在青紫泥上的吸附平衡均可采用Langmuir、Freundlish和Temkin等吸附方程来拟合，由Langmuir方程求得对青紫泥对铅的最大吸附量为14285 mg/kg。土壤吸附态Pb2+的解吸量随着Pb2+吸附量的增加而增加。

Abstract: In this paper, the adsorption and desorption properties of Lead in Jiaxing Garden Soil was studied. The result shows that Pb adsorption isotherms of tested soil are significantly fit for the esothermal equations of Freundlish, Langmuir and Temkin. The maximum Lead absorptive capacity of the soil is 14285 mg/kg. The Pb desorption was linearly related to the adsorption.
