1 Scope

This section provides the determination of bismuth antimony content. This section applies to the determination of bismuth in the antimony content. Measurement range (mass fraction). 0.0002% to 0.0025%.

2 Method summary

The sample is dissolved in nitric acid, hydrochloric acid medium, pentavalent antimony anions [SbCl6] - insoluble compound generation and malachite green, with toluene 640nm wavelength spectrophotometer after extraction measured absorbance.

3 Reagents

3.1 commercially available reagents 3.1.1 toluene. 3.1.2 nitrate (ρ1.42g/mL). 3.1.3 sulfate (ρ1.84g/mL). 3.2 solution 3.2.1 hydrochloric acid (1 + 2). 3.2.2 stannous chloride solution (100g/L). Weigh 10g of stannous chloride (SnCl2 · 2H2O) in 250mL beaker, add 50mL salt Acid (3.2.1) was stirred to dissolve and diluted with hydrochloric acid (3.2.1) to 100mL, and mix. 3.2.3 sodium nitrite solution (100g/L). 3.2.4 urea saturated solution. 3.2.5 malachite green solution (2g/L), one week after the configuration to use. 3.3 standard solution 3.3.1 Antimony standard stock solution. Weigh 0.1000g metal antimony (Sb mass fraction ≥99.9%) in 250mL beaker, 20mL sulfuric acid (3.1.3) dissolved by heating, remove cooling. Added 5mL hydrochloric acid (3.2.1) micro heat to dissolve the salts, cooled to room temperature, hydrochloric acid (3.2.1) moved into 1000mL volumetric flask and dilute to volume, and mix. This solution 1mL containing 0.1mg antimony. 3.3.2 Antimony standard solution. Pipette 10.00mL antimony standard stock solution (3.3.1) in 500mL flask with hydrochloric acid (3.2.1) diluted To the mark, and mix. This solution 1mL containing 2μg antimony.

4 Instrument

Spectrophotometer. Step 5 Analysis 5.1 Sample Table 1 sample was weighed, accurate to 0.0001g.
