Total Cyanide Analysis in Zinc Plating Baths

From Advanced Sensor Technologies, Inc.
 

 
Total cyanide is measured directly with a cyanide electrode due to the stability of the zinc-cyanide complex. The following procedure should be used as a general guide for the analysis since zinc baths may vary widely.
