| Abstract: | Adsorption behavior of organic pollutants in Shong-hua River was studied. The solid effect can be attributed to transfer of dissolved solid phase to liquid phase during the course of adsorption partitioning. Based on the results of our experiments, a mathematical model was developed for calculating adsorption partition coefficients (K). Thus, the K values for eleven compounds at different solid concentrations were obtained. |
