土壤腐殖质对苯酚的吸附作用研究

Study of the Effect Adsorption of Soil Humus to Phenolic

依据土壤腐殖质具有的优良吸附特性。本实验用土壤中的腐殖质和土壤矿物质与有机物质苯酚进行吸附测试。实验结果表明 :腐殖质对苯酚 (即使苯酚在很低的浓度下 )具有吸附作用。通过计算Freudlich和Langmuir的相关常数k、n和q0 、b ,证明了腐殖质对苯酚吸附机理是物理化学吸附 ,符合Freudlich等温吸附方程。实验数据说明土壤矿物质对苯酚的吸附作用极小。

Acording to the character of good adsorption of Soil humus has ,we test the Soil Humus and Soil mineral to phenolic.It turns out : the Soil humus is better to adsorpt of Phenolic ,but the Soil mineral has little effect on Phenolic.Thyough caculating the Freudlich and Langmuir adsotherm parameters (k,n,q0,b) the results proved Phenolic adsorbed by the Humus,was physico-chemical adsorption.And the adsorption to Freudlich isotherm equation is very good.
