AB-269 Titrimetric/potentiometric determination of ionic surfactants by two-phase titration using the Metrosensor Surfactrodes  
Titrimetric/potentiometric determination of ionic surfactants by two-phase titration using the Metrosensor Surfactrodes

This Bulletin describes the potentiometrically indicated «two-phase titration» of ionic surfactants in raw materials and various formulations using numerous practical examples. Two completely new designs of surfactant electrode, – the Surfactrode Resistant and Surfactrode Refill –, allow you to carry out this type of surfactant titration in s similar way to the classical «Epton titration» and with a high degree of automation.
The results obtained correlate to a high degree with those of the Epton titration. The toxic and environmentally hazardous chloroform can be replaced by alternative solvents such as ethyl isobutyl ketone or n-hexane.
