摘要：We examined aerobic biodegradation of sodium linear alkylbenzenesulfonate (LAS), sodium alkyl sulfate (AS), sodium alkylpoly (oxyethylene) sulfate (AES), sodium alkylphenylpoly (oxyethylene) sulfate (NES), sodium α-olefinsulfonate (AOS), sodium salt of fatty acid (soap), alkyl poly (oxyethylene) ether (AE) and p-alkylphenyl poly (oxyethylene) ether (APE) by bacterial sources from sewage sediments. In the course of biodegradation, the production of CO₂ was determined as the final products of carbon sources. The relationship between chemical structure and biodegradability of surfactants was compared. In terms of the final extent of biodegradation, the results of the aerobic biodegradabilities of surfactants were as follows : (AS, LAS, AE, AES, soap, AOS)»APE>NES. AS, LAS, AE, AES, soap and AOS were degraded to CO₂ to the same extent as glucose, but the time required to reach the final extent varied from 5 to more than 15 d depending on the chemical structure of surfactant. On the other hand, APE and NES were extremely resistant to aerobic biodegradations.
