Determination of AOT by Adsorptive Stripping Tensammetry in Connection to the Biopolimers Extractin by Reversed Micelles

Abstract

Bis(2ethylexyl) sodium sulfosuccinate (AOT) can be determined using Adsorptive Stripping Differential Pulse Tensammetry (ASDP) in concentration range 5 10⁻⁷ − 5 10⁻⁶ M. Higher concentrations can be determined by direct Differential Pulse Polarography.

The method is fit for determining AOT in reversed micelles and in water, a problem that is closely bound to the use of water-in-oil microemulsions for the selective extraction of biopolimers and their recovery in biotechnology.
