摘要：

An iron complex of dipicolinic acid (dipicH(2)), formulated as [Fe(dipic)(NO3)(H2O)(2)]2H(2)O (1), was prepared and characterized. Cyclic voltammetric response of bare carbon paste electrode surface in 0.10mol L-1 phosphate buffer containing 1 at pH = 7 and at various scan rates (10-70 mVs(-1)) was studied. The apparent charge transfer rate constant, ks, and transfer coefficient, a, for electron transfer [Fe(dipic)(NO3)(H2O)(2)]2H(2)O were calculated as 1/1 +/- 0.10s(-1) and 0.49, respectively. Thermal decomposition of 1 in the presence of polyethylene glycol led to the formation of Fe2O3.
