摘要: Blaedel等曾证明管式电极在层流条件下的扩散电流方程,随后在管式电极上对极谱催化电流进行了研究,但该理论只适用于化学反应非常快及非常慢的情况。Koichi等运用与Blaedel不同的处理方法,导出了通道电极上更为精确的催化电流方程。

Abstract: A theory of catalytic currents at a tubular electrode has been developed. The theory was applied to the catalytic currents observed in the reduction of ferric ions at the tubular gold electrode in the presence of hydrogen peroxide. The results showed that the diffusion coefficient and rate constant of the chemical reaction are 4.6×10-6cm2/sec and 105.8lit/mol·sec, respectively, in our experiments. Experimental data are in good agreement with the theory.
