Abstract
Sulphophenylmono- (SPC) and dialkanoic acids (SP2C), and nonylphenoxy acetic (NP1EC) and ethoxy acetic (NP2EC) acids were synthesized, chara cterized, and then determined by reversed-phase HPLC (RP-HPLC) togethe r with their parent compounds, the surfactants linear alkylbenzene sul phonates (LAS) and nonylphenol polyethoxylates (NPEO), respectively. T he separation procedures were applied to the analysis of raw sewage (i nfluent) and treated sewage (secondary effluent) as well as of sewage sludges. Both SPC and NPEC appeared to be key intermediates for the bi odegradation of LAS and NPEO.
