1 Scope

This section GB/T 23364 specifies the method for the determination of arsenic content in high-purity indium oxide. This section applies to the determination of the amount of high-purity indium arsenic, the measurement range (mass fraction) of 0.00001% to 0.0050%.

2 Method summary

Hydrochloric acid, hydrobromic acid solution, hydrazine sulfate arsenic is pre-reduced by distillation, absorption of condensed water. In hydride generator, the trivalent arsenic is Potassium borohydride as hydride reduction, with argon gas introduced into the quartz furnace atomizer, the fluorescence intensity measured on the atomic fluorescence spectrometer, calculated Arsenic content.

3 Reagents

Unless otherwise stated, use only identified as gifted class pure reagents and secondary distilled water or equivalent to its purity. 3.1 hydrochloric acid (ρ about 1.19g/mL). 3.2 hydrobromide (p about 1.49g/mL), after the use of distillation. 3.3 hydrazine sulfate. 3.4 solution of potassium borohydride (20g/L). Weigh 10g potassium borohydride, dissolved in 500mL of potassium hydroxide solution (5g/L), and mix well. If the A precipitate is filtered and used. The time is now equipped with. 3.5 hydrochloric acid (1 + 19). 3.6 arsenic standard stock solution. Weigh 0.1320g pre-dried at 105 ℃ 1h arsenic trioxide (mass fraction ≥99.99%), home In 300mL beaker, add 15mL of hydrochloric acid (3.1) and 5mL nitric acid (ρ about 1.42g/mL), heated and dissolved, evaporated to near dryness. plus 100mL of hydrochloric acid (3.1) dissolved salts, cooled and transferred to 1000mL volumetric flask, dilute with water to volume, and mix. This solution containing 1mL 100μg arsenic. 3.7 arsenic standard solution A. Pipette 10.00mL arsenic standard stock solution (3.6), placed in 200mL volumetric flask, dilute to the mark, Mix well. This solution 1mL containing 5μg arsenic. 3.8 arsenic standard solution B. Pipette 10.00mL arsenic standard solution A (3.7), placed in 100mL volumetric flask, dilute to the mark with water, mix uniform. This solution 1mL containing 500ng arsenic. 3.9 arsenic standard solution C. Pipette 10.00mL arsenic standard solution B (3.8), a 50mL volumetric flask, dilute with water to volume, and mix. This solution 1mL containing 100ng arsenic. 3.10 argon (volume fraction ≥99.99%).

4 Instrument

4.1 Distillation generator. 4.2 atomic fluorescence spectrometer, equipped with a special arsenic hollow cathode lamp. Atomic fluorescence spectrometer should meet the following specifications. --- Stability. Zero drift ≤5%, short-term stability RSD≤3% 30min inside; --- The detection limit ≤0.5ng/mL; --- Linear curve. the curve in 0 ~ 50ng/mL range, the correlation coefficient should ≥0.995. ......
