Abstract
The sodium salt of N-(N-bromo-C-tetradecyl betainyl)-C-tetradecyl betaine is presented as a gravimetrie reagent for the determination of gold. Two complexes have been isolated; one, precipitated from hydrochloric acid solution, containing 22.14% gold; the other, from hydrobromic acid solution, containing 18.01% gold. Both complexes may be dried to constant weight at 85° C, thus giving the advantage of a favorable weight factor. Determinations from hydrobromic acid solutions are more rapid and offer several other advantages. Optimum conditions have been established. The number of interfering ions is small and a method for thie separation of gold from these ions was developed. A procedure for the determination of gold in ore concentrates was applied to several samples with satisfactory results.
