Determination of surfactant biodegradation

ZHAO Yumei, QIN Yong, ZHANG Gaoyong(China Research Institute of Daily Chemical Industry, Taiyuan030001, China)  
Establishing and perfecting the method of determining degradation extent, including the process of preparation of actived sludge, cultivation, domestication and degradation of surfactant. Determining several familiar anionic surfactant and nonionic surfactant with this method. The result show that AES and C13 alcohol AEO7 can be degradated in 1d, nature alcohol AOS, AEO7 and TX-10 in 2 d, SAS and polyether in 3 d and LAS in 4 d, which are in accordance with the literature excellently. Those prove the reliability of this method. This method has the good duplication capability also.
