Abstract
Analysis of nickel-plating baths for various anions, organic acids and cations was performed by capillary electrophoresis. Analysis of these ions is important in relation to the effectiveness of the plating bath. Analysis of anions and organic acids in these plating baths was accomplished by direct UV detection at 185 nm and a phosphate electrolyte. Nickel and other cations were determined by indirect UV detection at 185 nm as well. Total analysis times of less that 7 min for anion and organic acid analysis and 5.5 min for nickel and other cations analysis could be achieved using these electrolytes. Changeover time from anion to cation analysis by capillary ion electrophoresis was accomplished in less than 10 min.
