表面活性剂对土壤中多氯联苯洗脱影响研究进展

多氯联苯（PCBs）作为典型的持久性有机污染物（POPs）,在环境中广泛分布且具有生物毒性,土壤中的多氯联苯可通过食物链在生物体中富集,对生物体产生危害。多氯联苯易与土壤紧密结合,由于其难以降解,故去除土壤中多氯联苯非常困难。利用表面活性剂的亲水性和亲油性,可促进土壤中PCBs释放到水体中,水体中的多氯联苯便于进一步处理,以减轻对生态的危害。该文综述了近年来国内外对于表面活性剂促进多氯联苯从土壤向水体中释放的研究进展,在阐释了表面活性剂促进土壤中多氯联苯洗脱机理的基础上,具体分析了影响促进作用的各种因素。

Surfactant Elution of Polychlorinated Biphenyls in Soil Research

Polychlorinated Biphenyls（PCBs） as a typical persistent organic pollutants（POPs）,widely distributing in the environment and biological toxicity of PCBs in soil can be enriched in organisms through the food chain,causing harm to organisms.Close combination of PCBs and soil,because of its difficult degradation of PCBs in the soil is very difficult to remove.Surfactant hydrophilic and lipophilic can promote the release of PCBs into the water in soil,PCBs of water is facilitate further processing to reduce the ecological hazards.The paper reviews the domestic and international promotion for surfactant release of PCBs from soil to water research progress in the interpretation of surfactant elution mechanism for PCBs in soil,based on detailed analysis of the impact promote the role of various factors.
