The cyclic voltammetric studies of the sulphate and oxalate complexes of Tii+/Ti3+ redox systems on Cu electrodes are reported and the results are compared with the behaviour on Hg and GC electrodes reported earlier. The easily reducible sulphate complexes are formed only on high Ti+ and H2SO4 concentrations as noticed in the earlier studies. The apparent heterogeneous charge transfer rate constant (kho) decreases by 40 times on Cu when compared to Hg. This rather unusual observation is probably associated with the greater blocking effect of the supporting electrolyte anions on Cu when compared to Hg. Added Cl-as well as so4'- exert even stronger blocking effect. The possible implication of the present study on the indirect electro-reduction technique used for the nitro compound reduction using Tii+/Ti3+ redox system is also discussed in some detail.
