Mechanism of Mg2+ transfer mediated by 1,10-phenanthroline across a water | 1,2-dichloroethane micro-interface

Cyclic voltammetry at a water | 1,2-dichloroethane micro-interface has been carried out to elucidate the mechanism of Mg2+ transfer assisted by 1,10-phenanthroline (phen). Micropipettes and microholes at polyester films were used to support the interface. The effect of phen and Mg2+ concentrations, pH, scan rate, and capillary radius were analyzed. The results indicated a TIC-TID mechanism coupled to the direct transfer of the complex Mg(phen)32+.
