Extraction of gallium from mixed acid solutions by tributyl phosphate and its application to activation analysis

  • V. Pfeifer


The extraction of gallium from chloride-containing solutions was investigated in detail. In the main, mixtures of hydrochloric acid and sulfuric acid were used as the aqueous phase, and the optimum extraction conditions have been established. Other acids and neutral salts increase the extraction rate very effectively, but nitric acid exhibits a detrimental effect. The extraction method has been applied successfully to the neutron activation determination of traces of gallium in insoluble aluminium oxide, which can be decomposed only by fusion with sodium pyrosulphate.
