摘要: 利用摇床法对4种阳离子表面活性剂M-300、M-301、M-302和十二胺的生物降解性进行了评价。实验结果表明,4种阳离子表面活性剂20 d的净降解率分别为44.04%、72.65%、32.14%、76.98%,依据评价标准,M-301和十二胺属于易降解药剂,M-300和M-302属于可降解药剂。

Abstract: Shaking table process is applied to evaluating biodegradability of four cationic surfactants M-300,M-301,M-302 and lauryl .The results showed that the net biodegradability rate of the four cationic surfactants in twenty days is 44.04%、72.65%、32.14%、76.98% respectively. according to the evaluation standards, M-301 and lauryl amine are easily biodegradable, while M-300 and m-302 is biodegradable.
