摘要
In this paper, the adsorption capacity of loess for mineral oils and the influence of temperature, pH, organic matter content and salt contents on the adsorption were investigated by laboratory static experiments. The results showed that adsorption of oils on loess conforms to Langmuir isotherm. Adsorption capacity decreased with the increase of temperature and pH. Adsorption tended to increase with the decrease of diameter of soil particles. There was a positive linear correlation between the adsorption and the organic matter content or salt contents. With the organic matter content and salt content increasing,the adsorption increased.
