  • The Analysis of Cyanide Silver-Plating Solutions
    RP384 THE ANALYSIS OF CYANIDE SILVER-PLATING SOLUTIONS By R. M. Wick ABSTRACT Methods for the analysis of cyanide silver-plating solutions were studied, including the determination of free cyanide, total cyanide, carbonate, chloride, ammonia, silver, iron, copper, and mercury. Electrometric titrations showed that the Liebig method for alkali cyanide is correct to better than 0.2 per cent. Addition of iodide makes the method still more accurate and overcomes the effects of impurities on the titration. The nonagreement of the Liebig and Hannay methods was studied by electro- metric titrations, which showed that the visual Hannay method gives high results although the electrometric Hannay titration is accurate. The determination of total cyanide was accomplished by distillation with sulphuric acid, and of total effective cyanide by titration with iodine. Silver may be separated as silver sulphide, by precipitation with zinc, or by decomposition with acid, after which a determination by any standard method is applicable. Carbonate may be determined by precipitating and filtering out barium car- bonate and titrating it with acid or by titrating a sample with acid after adding silver nitrate to combine with the free cyanide. The usual method for the determination of chloride involves prolonged treat- ment with nitric acid, which converts the precipitated silver cyanide to silver chloride. A new method for separating chloride was investigated in which the silver is precipitated as sulphide and the iron is removed by precipitation as manganous ferrocyanide. The chloride in the filtrate can be determined by the usual methods. Iron and copper can be determined by the regular analytical methods after decomposition of the plating solution with sulphuric acid.
