| Abstract: | The natural degradation behavior of linear alkyl benzene sulphonate(LAS) in environment was an key point in the environmental research.The process and mechanism of LAS natural degradation in environment including water and soil were elaborated,and the major influential factors of LAS degradation efficiency including LAS molecular structure,its initial concentration,microorganism quantity,temperature,oxygen content and pH value were analyzed.It would provide good reference and foundation for LAS extended application and its sewage treatment in the future. |
