摘要

建立并应用库仑-称重法测量电镀锡板镀层.该法不需考虑库仑法中的电量、电流效率和电化当量等影响因素,同时克服了称重法在判断溶解终点时的盲目性,具有较高的精度,SD小于0.04g/m2,RSD不超过0.36%.

Abstract

The coulometric-weighing test method was established and applied to determine the tin coating mass for electrolytic timplate. The effects of electric quantity, the current efficiency and the electrochemical equivalent in the coulometric test method were overcome. the inaccuracy in the determination of final point at the anodic dissolution curve in the weighing method was avoided when applied to the electrolytic timplate, higher accuracy was obtained, the SD is less than 0.04 g/m~2,RSD is as small as 0.36%.
