Biodegradation mechanism of linear alkylbenzenesulfonate-14C
- 1. Tokyo Metropolitan Isotope Research Center (Japan)
Description
The biodegradation of linear alkylbenzenesulfonate-14C (LAS-14C) tagged with 14C at the linear side chain was studied on activated sludge by tracer method in addition to the methylene blue method which is widely employed in the biodegradation of LAS. It was found that there were three periods of rapid adsorption period, acclimation period, and degradation process. The radiolysis of dodecylbenzenesulfonate was studied on irradiating by 5000 Ci 60Co source. The decomposition products were identified by GLC and GC-MS spectrometry after desulfonation. 1-Tetralone, 1-indanone, 4-methyl-1-tetralone, naphthalene et al. were found in them. (author)
