Surfactant-selective electrodes : Part I. An improved liquid ion-exchanger

Abstract

An improved electrode selective to the dodecylsulphate anion is described, which has no apparent effect on micellar properties. Electrodes selective to a variety of surfactant types have been prepared and the manufacture of electrodes specific to single alkyl chain length surfactants is discussed. An example is given of their use in the study of the precipitation of commercial surfactants.
