Abstract
Abstract The anionic surfactant is extracted into chloroform as a neutral complex with the bis(ethylenediamine)copper(II) cation, and copper(II) is determined spectrophotometrically after addition of 1-(2-pyridylazo)-2-naphthol and diethylamine. With a 200-ml water sample, the limit of detection is 5 μg l -1 (as linear alkyl sulphonic acids). The method is simple and is directly applicable to fresh, estuarine and marine waters.
