摘    要:研究了铅在黄松土上吸附一解吸特性。结果表明,铅在黄松土上的吸附平衡均可采用Langmuir,Fretmdlish和Temkin等吸附方程来拟合,由Langmuir方程求得黄松土对铅的最大吸附量为12500mg/kg。土壤吸附态Pb^2+的解吸量随着Pb^2+吸附量的增加而增加。

关 键 词:  菜园土  吸附  解吸

Abstract:In this paper, the adsorption and desorption peculiarity of lead in garden soil in Hangzhou city was studied. The result showed that Pb adsorption isotherms of soil tested were very well fitted for the isothermal equations of Freundlish, Langmuir, and Temkin. The maximum absorption capacity of lead by the soil was 12 500 mg/kg. The desorption rate of Pb from the soils increased with increasing the rates of adsorption by the soil.
Keywords:lead   garden soil   adsorption   desorption
