Determination of Silver in Electroplating Baths by Controlled-Potential Coulometry.

摘要

A method has been developed for the accurate and precise determination of silver in cyanide electroplating baths. The procedure involves wet ashing an aliquot of solution and then measuring the silver by controlled-potential coulometry (CPC). The precision and accuracy of the method are 0.05percent and 0.2percent,respectively.
