• Most residential wastewaters containing synthetic detergents are discharged into the environment without receiving any treatment. The main component of these synthetic detergents is an anionic surfactant typified by linear alkylbenzene sulfonate (LAS). Accordingly, a highly sensitive and simple method of determination of LAS by high performance liquid chromatography in conjunction with concentration by an octadecylsilica (ODS) minicolumn was developed. This method showed high values of 93.6%-95.5% in the recovery/addition rate and a coefficient of variation below 5%. By application of the present method to the analysis of river waters, the suspended component was shown to be responsible for the disappearance of LAS at low temperature.
