Quaternary Phosphonium Salts

The determination of the adsorbed film characteristics at the interface between methanolic solutions of quaternary phosphonium salts and the Hg electrode is carried out by means of time dependent capacitance measurements. The maximum surface concentration, the area per adsorbed particle and the orientation of methyltriphenyl-, cyclopropyltriphenyl-, and n-butyltriphenylphosphonium cations are derived by two methods, the first of which is free of isotherm assumptions and the second involves an adsorption isotherm obeyed by the system under examination.

Method Of Determination

The minimum on the polarographic curves for Bi(III) reduction in HCl solutions occurring when small amounts of surfactants are present can be used for their quantitative determination. The form of the polarograms was examined with respect to the concentration of the surfactant, and the range of concentrations in which the method of determination can be used is discussed.
