Determination of the amount of arsenic and bismuth Hydride generation - atomic fluorescence spectrometry, potassium bromate Titration and diethyl dithiocarbamate Silver spectrophotometry1 ScopeGB/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 Unless otherwise indicated in the analysis using only recognized as analytical grade reagents and distilled or deionized water or equivalent purity. 2.2.1 Potassium Chlorate. 2.2.2 hydrochloric acid (ρ = 1.19g/mL), pure class distinctions. 2.2.3 hydrochloric acid (124). 2.2.4 nitric acid (ρ = 1.42g/mL), pure class distinctions. 2.2.5 nitric acid (11). 2.2.6 nitric acid (124). 2.2.7 sulfuric acid (ρ = 1.84g/mL). 2.2.8 sulfuric acid (11). 2.2.9 ammonia water (ρ = 0.90g/mL). 2.2.10 ammonia (298). 2.2.11 sodium hydroxide solution (200g/L). 2.2.12 sodium hydroxide solution (2g/L). 2.2.13 ammonium ferric sulfate solution. Weigh 84.4g ammonium ferric sulfate [FeNH4 (SO4) 2 · 12H2O] were dissolved in 500mL of water, add 20mL Sulfuric acid (2.2.8), diluted with water to 1L, mix this solution 1mL containing 10mg iron. 2.2.14 thiourea - ascorbic acid solution. Weigh 5g thiourea and ascorbic acid, dissolved in water and diluted to 100mL, and mix. 2.2.15 solution of potassium borohydride (5g/L ~ 25g/L).
