| Abstract: | The transfer of Mg2+, Ca2+, Sr2+ and Ba2+ across H2O/nitrobenzene interface facilitated by 10 H2O soluble and 2 H2O insoluble crown ethers was studied. The possible mechanism of the electrolysis reactions in different systems were: (1) the transfer of metal ion followed by a complexation in the nitrobenzene phase, (2) the simple transfer of complex ion formed in the H2O phase, (3) the transfer of metal ion preceding with a complexation in the H2O phase or followed by a complexation in the nitrobenzene phase resp., (4) the process mixed up with several charge transfer reactions, and the irreversible charge transfer reactions. Thermodn. data were estimated from the voltammograms. |
