土壤中有机碳含量对三氯乙烯的吸附影响实验
The effects of different contents of organic carbon on the adsorption of trichlorinated hydrocarbon in soil
摘要
Abstract
The adsorption of organic contaminants in soil is one of the most important factors affecting the migration and transformation process of these organic contaminants. Using batch experiments, this paper studied the adsorption behaviors of Trichloroethylene (TCE) in soil samples with different contents of organic carbon. The results indicate that the adsorption capacity is significantly correlated with different contents of organic carbon. There exist critical threshold values (f_∝~*) of organic carbon contents. The minimum f_∝~* and the maximum f_∝~* are equal to 0.702% and 1.831%, respectively. The TCE adsorption capacity does not vary greatly with the increasing of organic carbon contents when f_∝ is lower than 0.702% . Nevertheless, the TCE adsorption capacity varies considerably with the increasing of organic carbon contents when 0.702%<f_∝<1.831%. When f_∝ is higher than 1.831%, the TCE adsorption capacity does not vary remarkably again with the increasing of organic carbon contents.关键词
