Abstract	Zn, Ni 및 Co ion의 음극반응속도를 Polarograph로써 몇 가지 지시전해액과 온도에서 Randles법으로 측정하였다. Zn의 속도치는 Randles들의 측정치와 20% 오차내에서 일치하였다. Ni 와 Co ion에 대한 값은 문헌에 나타나 있지 않으나 전보의 다른 방법에 의한 値와 비교하면 적당한 값이라고 볼 수 있다. Randles법에 의한 속도치를 써서 Kambara들이 제안한 Parameter x,y(z)를 구하고 이들 사이의 관계을 고찰하였으며 log y vs. log z 사이에 일종의 곡선관계가 있음을 발견하였다. The electrode reduction velocities of Zn, Ni and Co ions at DME in various supporting electrolytes and temperatures were measured by Randles' method. The values for Zn ions agreed with Randles' values within 20%. As mentioned in the auther's previous paper, the observed values of Ni and Co ions were considered to be reasonable. In the present work the curves log y vs. log z for the various metals in the range of 20~35℃ were obtained.
