Abstract
PURPOSE:To easily execute the measurement by split-phase titration of various kinds of ionic surfactants by using a specific split-phase indicator alone or previously preparing two kinds of dyes which are suitable for use under an alkaline condition and acidic condition and are approximately equal in the wavelength of absorption maximal as the split-phase indicator. CONSTITUTION:Direct titration or back titration is executed by using a heterogeneous system consisting of the ionic surfactant to be inspected, the water contg. the split-phase indicator forming a complex with the surfactant and water insoluble org. solvent as a liquid to be titrated and the surfactant having the charge reverse from the charge of the surfactant or the same charge as a titrating liquid, in a method for measuring the ionic surfactant by the split-phase titration. Any among orange I, Amaranth and New Coccine is used alone as the split-phase indicator. Two kinds of the dyes which is suitable for use under the alkaline condition and the acidic condition and are approximately equal in the wavelength of the absorption maximal are otherwise previously prepd. and the dyes suitable for the respective conditions are selectively used.
