Abstract A procedure for determination of anionic surfactants in sea water is described for concentrations in the range 10–500 ug/1. This method involves formation of an ion-pair between orthophenahthroline-copper (II) cation and anionic surfactant which is extracted by methylisobutylketone; copper being determined in the solvent by atomic absorption spectrophoto-raetry. The procedure can been also used to determine anionic surfactant in fresh water. Determination of cationic surfactants is possible after changes of the original experimental conditions. 相似文献
