摘要
通过室内静态实验 ,研究了石油类污染物在黄土地区土壤中的吸附行为。初步探讨了石油类污染物在黄土高原地区土壤中的吸附特性。实验表明石油类污染物在黄土地区土壤中的吸附符合Henry吸附模式 ,吸附分配系数为 1 34 .0 7;黄土对石油类的吸附速度很快 ,1 0min内即可接近吸附平衡。水土比、温度、pH、TDS等对吸附有一定影响。
Laboratory static experiments were conducted to investigate the adsorption capacity of loess for mineral oils. The results show adsorption of oils on loess conform to Henry isotherm with partition factor of 134.07 and very high adsorption velocity, approaching equilibrium in just 10 minutes. In this paper, effects of SS, temperature, pH and total dissolved salts (TDS) on the adsorption were also discussed.
