| 摘 要： | 选取某采油厂不同有机碳含量的表层土壤作为吸附剂,采用批实验方法对原油中代表性组分苯和甲苯的单组分吸附和双组分竞争吸附行为进行了研究。研究表明,单组分溶液中,苯和甲苯在土壤中的吸附符合线性规律,吸附能力与土壤有机碳含量成正比;双组分溶液中,苯和甲苯共存时存在竞争吸附,土壤对它们的吸附小于单组分时的情况。竞争吸附的结果说明,除分配吸附以外,介质表面点位对苯和甲苯的吸附也起着重要的作用。

| Abstract: | The sorption of components of crude oil to soils affects their transport and transformation.In this study,batch experiments were carried out to investigate the sorption and competitive sorption of benzene and toluene to soils with different amounts of organic carbon.The results of single-solute solution experiments showed that the sorption of single compound to soils could be described by a linear sorption isotherm,and the sorption capacity was proportional to the soil organic carbon content.In bi-solute so... |
