WebJan 31, 2002 · 31 Jan 2002 by Metrohm (UK) Surfactant titrations in difficult matrices without the restrictions on chloroform use present in the Epton method can be solved using the Surfactrode from Metrohm Traditionally surfactant titrations have been performed using the classic Epton titration method. WebA method has been developed for the determination of anionic surfactants in aqueous solution. It is based on solvent extraction titration of an ion pair. Zephirmine (tetradecyldimethyl ammonium chloride) is used as a titrant with tetrabromophenolphthalein ethyl ester as an indicator in the presence of chloroform. In the two-phase titration …
