Title: Separation and Enrichment of Ga and In with Ion-exchange Resin and their Determination by Platform Graphite Furnace Atomic Absorption Spectromtery
Abstract: The conditions for separating and enriching Ga and In with 003 X 7 ion-exchange resin and the determination of Ga and In by GFAAS (Graphite Furnace Atomic Absorption Spectrometry) are systematically studied. The Ni and V are used as the matrix modifer for the determination of Ga and In. In the range of pH 0. 5-7, the Ga and In are adsorbed selectively, and eluted with a solution of 3 mol/L HNO3. The detection limit is down to 1. 52 ng/ml for Ga, 0. 976 ng/ml for In. Analytical results of national standard reference rock samples by this method conform to the recommended values.
