| 摘 要： | 通过静态吸附实验,研究了兰州地区黄土对含油废水中石油类污染物的吸附作用,并对温度、pH、土壤粒径、有机质含量和含盐量等影响吸附作用的因素进行了分析。实验结果表明:该类型黄土对可溶性石油饱和溶液的吸附等温线符合Langmuir吸附模式,其吸附能力随温度、pH的升高而降低;吸附量随土壤粒径的减小呈增大趋势;吸附量与土壤有机质含量、含盐量呈线性关系,随着有机质含量、含盐量的增高吸附量增大。

| Abstract: | 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 adsorpti... |
