Abstract :An HPLC method was developed to determine linear alkylbenzene sulphonates insert ignore into journalissuearticles values(LASs); and their biotransformation products sulphophenyl carboxylates by isocratic chromatography using two C18 columns in series. Solid-phase extraction with a insert ignore into journalissuearticles values(C18); cartridge was employed to isolate LAS from sediment and sewage effluent samples. Sodium perchlorate and ammonium perchlorate were used as ion pair agents. The recovery of the compounds was 94% \pm 2 and 98% \pm 2 respectively for sediment and sewage effluent. It was demonstrated that it is possible to separate LAS compounds and their isomers and homologues using this system.
