Determination of Nickel, Nickel Chloride Hexahydrate and Boric Acid in Nickel Sulfamate Plating Solutions by Titration

摘要

The chemical literature lacks analysis methods for the determination and adequate monitoring of nickel, nickel chloride hexahydrate and boric acid in nickel sulfamate plating solutions. Methods are given here that provide acceptable analysis and monitoring of these chemical species in this nickel sulfamate plating process. The optimum respective operating range of nickel, nickel chloride hexahydrate and boric acid are 53.0 -94.0 g/l, 6.0- 30.0 g/l, and 30.0-45.0 g/l. The resulting precisions are in the range of 0- 0.3 g/l providing adequate monitoring of these plating solutions supported by two years of testing. chemical analysis, nickel, nickel chloride hexahydrate, boric acid, nickel sulfamate plating solutions, titration.
