摘　　要：就近年来人们利用超临界二氧化碳流体对有机污染物污染的土壤所做的研究工作以及所取得的成果进行了总结。Supercritical carbon dioxide fluid has low toxicity,high purity,low cost,mild critical parameters,a good ability to dissolve many organic compounds.Furthermore,low viscositics of supercritical carbon dioxide fluid combined with high solute diffusivities in fluid result in superior mass transfer characteristics.This method has been attracting considerable attention in environmental chemistry.This paper makes a conclusion about proceedings of supercritical carbon dioxide fluid extraction of organic contaminant from soil in the past decade.

关 键 词：超临界二氧化碳 土壤 有机污染物 污染源
