The transfer of Na+ facilitated by emulsifier OP across the water/nitrobenzene interface has been studied by semi-differential cyclic voltammetry, and a new method for the determination of emulsifier OP was established. The proposed method is simple, easy and effective.展开更多
The transfer of lanthanum ion facilitated by diantipyrylmethane (DAM) across the water/nitrobenzene (w/nb) interface and the adsorption of emulsifier OP at the w/nb interface has been studied by the cyclic voltammetry...The transfer of lanthanum ion facilitated by diantipyrylmethane (DAM) across the water/nitrobenzene (w/nb) interface and the adsorption of emulsifier OP at the w/nb interface has been studied by the cyclic voltammetry. The mechanism of the charge transfer reactions is discussed. It has been concluded that the transfer of rare earth metal ion (La3+) facilitated by neutral ionophore (DAM) at the w/nb interface is E mechanism and the nonionic surfactant (emulsifier OP) can participate in the charge transfer process M an ionophore, charge transfer catalyst and inhibitor.展开更多
