The monomer N,N'-bis(2-pyrrol-1-yl-propyl)-4,4'-bipyridine(bpb) was electrochemically polymerized on the glassy carbon electrode surface, which was modified with 1:1 ratio of erichrome black T(EBT) and glutathione(GSSG) to give a type of GC/poly-bpb, EBT, GSSG electrode for depositing Zn(Ⅱ). The diffusion coefficients of the incorporated ions were 2.43×10^-15 and 9.14×10^-15cm²s^-1 before taking Zn(Ⅱ) ions and after them respectively. The modified electrodes are stable at the electrode process. The polymerized poly-bpb of 2.83×10⁴gmol^-1 can deposit 2.15×10⁴gmol^-1 of Zn(Ⅱ). The number of pumping ions involving in the redox procedure at 0.77 V was 81.7% of the captured 180 ions into the polymer matrix, which was 3 times larger than that of the electrode modified with EBT alone.
