| 摘 要： | 由于直链烷基苯磺酸钠(Linear Alkylbenzene Sulfonates,LAS)在纺织、化工等行业中的广泛运用,LAS成为环境中最常见的具有代表性的一类有机污染物,其吸附、降解等环境行为受到普遍的关注.现结合近几年对LAS的试验研究成果,对影响LAS在环境中的吸附、降解行为的因素,包括土壤类型、温度、初始浓度、微生物活性等做了初步总结.由于LAS在不同环境中的吸附、生物降解等行为十分复杂,对于其在环境中的吸附机制和一些土壤影响因素尚难以得到一致结论,需进一步深入研究.

| Abstract: | As we know,linear alkylbenzene sulfonates(LAS) is a kind of organic pollutants that was most familiar and representative in the environment.Its environmental behavior including sorption and degradation has drawn wide attention.This paper reviewed the results of recent studies on LAS and primarily discussed the environmental factors that affect the sorption and biodegradation of LAS.But the behaviors were so complicated that many mechanisms involved were still not very clear.Further studies were needed. |
