有机污染物在自然沉积物上的吸附行为——固体浓度对吸附分配系数的影响

Adsorption Behavior of Organic Pollutants on Natural Sediments; Effect of Solid Concentration on Adsorption Partition Coefficients.

本文研究了11种有机污染物在松花江沉积物上的吸附行为,发现吸附分配系数随固体浓度的改变而变化.原因为吸附平衡过程中,有机碳和悬浮微粒由固相扩散到液相.同时在实验基础上建立了数学模型,并计算了11种有机物的吸附分配系数.

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.
