Determination of Anionic Surfactants Employing Potentiometric Sensors—A Review

Abstract

This article describes the ongoing evolution of potentiometric sensors as employed in the field of anionic surfactants, beginning with the first reports published in the 1960s. Although the 1970s saw an increased use of such devices due to the adoption of PVC matrices, it is only relatively recently that commercial electrodes for these species have been available to industry. The latest developments, particularly the study of new polymer formulations and their application to other transducing devices, are also discussed.

Keywords:

• anionic surfactants
• ion-selective electrodes
