Electrochemical behaviour of EOP at the liquid/liquid interface and its determination
Abstract:
A new approach to the determination of emulsifier OP (EOP, a nonionic surfactant) is proposed, based on the voltammetry of the EOP facilitating Ca(2+) transfer across the water/nitrobenzene (w/nb) interface. The peaks obtained with cyclic voltammetry at the w/nb interface correspond to the transfer of the coordination complex ion [Ca(EOP)](2+) from the aqueous to the nonaqueous phase. The calibration graph is linear in the range of 1.5x10(-5)-5x10(-4) mol l(-1). The ionic surfactants have a very minor effect on detection.
