Chernov'yants, E. Lykova] Diiodobromides of P-containing organic cations, 3-carboxypropyltriphenylphosphonium (I) and tetraphenylphosphonium(II), were identified and quantitatively determined by capillary electrophoresis using an unmodified fused-silica capillary. The procedure for the quantitative determination of I and II by capillary electrophoresis allowed the organophosphorus compounds to be determined in the concentration range from 0.20 to 6.0 mM (RSD≤1%). The spectrophotometric method based on the conversion of diiodobromides to the corresponding triiodides (ε290=4.6 ×104,ε367=2.5 ×104) and followed by the measurement of the intensity of the band of the triiodide ion charge-transfer (RSD≤2%) was proposed to determine iodohalides of P-containing cations.
