1 Scope

This part of GB/T 14353 specifies the determination of tin in copper ore, lead ore and zinc ore by hydride generation atomic fluorescence spectrometry. content. This section applies to the determination of tin content in copper ore, lead ore and zinc ore by hydride generation atomic fluorescence spectrometry. Measuring range. 0.001% to 1.0% (mass fraction).

2 Normative references

The following documents are indispensable for the application of this document. For dated references, only dated versions apply to this article. Pieces. For undated references, the latest edition (including all amendments) applies to this document. GB/T 6682 Analytical laboratory water specifications and test methods GB/T 14505 General rules and general rules for chemical analysis of rocks and ores

3 Principle

The sample is dissolved in hydrochloric acid and nitric acid, and the pH of the sample solution is adjusted to 4.5 with ammonia water. The iron hydroxide is used as a carrier to make tin and Fe(OH)3 together. Precipitation, separation of copper, lead, zinc. The tin-containing precipitate and the acid-insoluble matter are melted by sodium oxide, extracted by hot water, and subjected to secondary separation with the interference component. in In the acidic medium, tartaric acid-thiourea-ascorbic acid is added as a masking agent, and tin reacts with potassium borohydride to form hydrogen sulfide, which is loaded into the quartz by argon gas. The atomizer is decomposed into atomic tin, and the high-intensity hollow cathode lamp of tin is used as an "excitation" light source to make the tin atom emit fluorescence, and the fluorescence of tin is strong. The degree is proportional to the concentration of tin within a certain range. Determination of the fluorescence intensity of tin by atomic fluorescence spectrometry, based on atomic fluorescence intensity Calculate the tin content in the sample.

4 reagents or materials

This section uses analytically pure reagents and secondary water in accordance with GB/T 6682, unless otherwise stated. 4.1 sodium peroxide. 4.2 Sodium hydroxide solution. ρ=250g/L. 4.3 Hydrochloric acid solution (1 1). excellent grade pure. 4.4 Nitric acid solution (1 1). 4.5 Nitric acid solution (1 4). 4.6 Sulfuric acid solution (1 1). Warning - improper dilution is dangerous ......
