Abstract
PSC (potassium silver cyanide), phosphate, free cyanide and berate componen ts constituting silver plating solutions were simultaneously analyzed with a capillary ion analyzer, using a chromate buffer at pH 11, Detection of ea ch ion was achieved using on-column indirect photometry at 254 nm, The four species were simultaneously analyzed. Simultaneous analysis is a needed an d powerful technique for process chemical control in the metal finishing in dustry.
