五种南方土壤的硫酸根吸附特性

SULFATE ADSORPTION CHARACTERISTICS OF FIVE SOILS IN SOUTHERN CHINA

摘要: 我们研究了南方五种不同母质类型土壤的硫酸盐吸附,并确定这些土壤的吸附能力及描述硫酸盐吸附的吸附方程。吸附能力以赤砂土为最高,其次为第四纪红土及黄泥土,而油砂土及灰棕紫泥土较低。本实验比较了各土壤的五种离子吸附方程,Freundlich,Tcmkin、直线方程、二种指数方程。重庆郊区的油砂土及灰棕紫泥土以Temkin方程为最佳,贵州黄泥土及广西赤砂土拟合Freundlich方程,广西第四纪红土拟合直线方程。

Abstract: Sulfatc adsorption experiment has been carried on five typical soils in southern China.The adsorption equations of different types of soil were investigated in order to provide a scientific basis for studies the effects of acid rain on soils.
