説明

The biodegradability of some anionic surfactants in the river die-away test was studied. The biodegradability was evaluated by the methylene blue activity and total organic carbon (TOC). Sodium α-olefin sulfonate (AOS), sodium n-dodecyl sulfate (SDS), sodium polyoxyethylene glycol n-dodecyl ether sulfate (DES), sodium linear alkylbenzene sulfonate (LAS), sodium branched alkylbenzene sulfonate (ABS) and sodium stearate (Soap) were used as test material in this study.<BR>It was observed that these surfactants, except ABS, were biodegraded intoneinorganic substances in this experimental period. The relative biodegradation rate, estimated by methylene blue activity was SDS_??_DES>AOS>LAS>>ABS, and estimated by TOC was Soap_??_SDS_??_AOS>DES>LAS>>ABS. The methylene blue activity was disappeared in shorter period than TOC.
