Controlled potential difference electrolysis interface

Evolution ofC02 by Controlled Potential Difference Electrolysis at the W/NB Interface. The evolution of CO2 was also observed when controlled potential difference... 

Controlled potential electrolysis was carried out for 4 h by applying a definite potential difference, iiappb at the stationary interface between W containing 10 M NADH and 0.01 M borate buffer and DCE containing 10 M CQ, and the concentration of NADH in W after the electrolysis was determined spectrophotometrically. Ratios of concentrations of NADH reacted (and hence decreased) by the electrolysis are plotted as curve 1 in Fig. 6 as the function of itappi-... 

The evolution of C02 was also observed when controlled potential electrolysis was carried out by applying a definite potential difference at the W/NB interface in the cell of Eq. (6)... 

Figure 6(b) includes the voltammograms at the Wl/LM and LM/W2 interfaces and the VITTM at the stage when 10 and 40% of have been transferred from W1 to LM and W2, respectively, by the electrolysis at FW1-W2 = +0.20 V. Although the decrease in the current for the transfer of from W1 to LM causes shifts in lm/w2 (from C to C ) and wi/lm (from D to D ) similarly to the behavior with DB18C6, the transfer of Na+ from Wi to LM hardly occurs in the case with valinomycin, because the difference in potential between the wave for the transfer of K" " and that of Na+ from Wl to LM in the presence of valinomycin is much larger than the shift in iiwi/LM- Therefore, effective separation of K+ from Na+ by electrolysis under the controlled membrane potential is expected if valinomycin is used as the ionophore in the LM instead of DB18C6.
