Title
Determination of sulphate content of anionic surfactants : sodium di-2-ethylhexylsulphosuccinate
Author
Abstract
A simple nephelometric method for the determination of sulphates in the anionic surfactant Aerosol-OT is described. The method is based on the formation and stabilization of a barium sulphate dispersion in a water-alcohol mixture and measurement of the turbidity at 650 nm. Beer's law is followed for sodium sulphate concentrations in Aerosol-OT ranging from 0 to 7000 μg/g. The lower determination limit is about 100200 μg/g and the reproducibility about 5% for typical commercial Aerosol-OT samples. The method can also be used for other anionic surfactants by adjusting the water-ethanol ratio of the solvent.
