Abstract

For the Department of Revenue ntelligence a composite scheme was developed for the analysis of the various constituents of gold-aluminiumcopper alloy. . n this method, the aqua regia alone was not effective in dissolving the sample. Gold was determined by electrogravimetry and potentiometry, aluminium, after its isolation was determined by spectrophotometry using oxine as the reagent . For the determination of trace amounts of copper in the sample, the diethyl dithiocarbamp; to method was found to be inadequate and hence a new method based13; on neoeuproin was developed.
