1 Scope
GB/T 3884 This section specifies the method for determination of arsenic and bismuth in copper concentrate content.
This section applies to the determination of arsenic and bismuth in copper concentrate content. The method of measuring a range of 0.010% to 0.10% arsenic, 0.010% bismuth ~
0.70%; Method 2 Determination of arsenic in the range > 0.10% to 2.00%; Method 3 Determination of arsenic in the range of 0.010% to 0.10%.
2 1 Hydride Generation - Atomic Fluorescence Spectrometry
2.1 Method summary
Sample with nitric acid, sulfuric acid dissolved in ammonia solution, the iron for the carrier, and other arsenic and bismuth and copper impurities separation. With pre-ascorbic acid
Reduction in residual copper thiourea in the hydride generator, arsenic and bismuth are reduced potassium borohydride as hydride, import original quartz furnace with argon
Son of the vessel, measuring the fluorescence intensity on the atomic fluorescence spectrometer.
2.2 Reagents
