The purpose of the work was to develop a fast accurate method for the determination of nickel in phosphating baths. To accomplish this, basic nickel carbonate is known amounts was added to aliquots of phosphating solution. To prevent precipitation of solids during analysis, hydrochloric acid was added to the aliquots. A number of samples, taken from several different phosphating baths and stabilized in the manner described above, were subjected to X-ray spectrographic analysis for nickel. The results obtained from these analyses showed that the method described is a fast accurate method for the determination of nickel in phosphate baths. Author
