Abstract
Polarography에 의한 반응속도측정법은 여러가지가 있고 또 많이 연구되어 왔다. 그러나 그의 응용은 그렇게 많지 않으며, 본 실험에서는 Delabay의 도해법과 Koutecky식을 이용하여 몇 가지 ion의 음극반응속도를 구하고 이들 Data를 써서 간이속도식을 검사하였다.

The electrode reduction velocity constants of Calcium, Nickel and Manganese (Zinc) ions in various supporting electrolyte solutions and temperatures were measured by polarography. The rate constants of those ions calculated by Delahay's graphimetric method and Koutecky's method were matched in 50% of experimental error. This error would be accountable because of the application of thier approximate method. But there are magnificent differences between those values and Randles and Sentioomerton's. We, also, have attempted to deduce the simplified relation between velocity constant and electrocappilary characteristics, computing the velocity constant simply and rapidly, on which Kambara, lshii and Imai, Adachi had studied and established thier related equations using parameter x, y and z, for some limited range of x. And we have extended the equation to the wider range of y value than they did for the above mentioned ions.
