Adsorption Behavior of p-chlorophenol on the Reed Wetland Soils
Investigation of the adsorption behavior of organic pollutants by soils is fundamental to simulating and eventually predicting their transport in environmental compartments. The adsorption behavior of p-chlorophenol by soils from yancheng reed wetland was studied in a series of batch equilibration experiments, and experiments were analyzed by Langmuir and Freundlich isotherm equation. Results showed that the adsorption process could be described with both Freundlich and Langmuir isotherms. But the empirical Freundlich equation fit the behavior better, and the highest correlation coefficient, r=0.9690, was obtained. Parameters affected the adsorption property of p-chlorophenol, such as solution pH, ionic strength and soil organic matter, were also studied. Adsorption capacity increased with lower pH, higher ionic strength and soil OC.
