1 Scope

This method specifies the method for the determination of antimony content of lead anode mud. This method is applicable to the determination of lead anode mud antimony content was measured in the range of from 5.00% to 13.00%.

2 Method summary

Sample with a mixed acid of hydrochloric acid and nitric acid decomposition, plus antimony tartrate complex. In hydrochloric acid medium, atomic absorption spectrometer wavelength 217.6nm at using air - acetylene flame measured absorbance of antimony.

3 Reagents

Unless otherwise indicated in the analysis using only recognized as analytical grade reagents and distilled or deionized water or equivalent purity. 3.1 hydrochloride (ρ1.19g/mL). Nitrate 3.2 (ρ1.42g/mL). 3.3 hydrochloric acid (119). 3.4 mixed acid. hydrochloric acid, nitric acid (31). 3.5 tartaric acid solution (200g/L). 3.6 Antimony standard stock solution. Weigh 0.5000g metal antimony (wSb≥99.99%), placed in 250mL beaker, add tartaric acid and 5g 30mL of nitric acid (3.2), dissolved by heating on a hot plate, remove, cooled to room temperature, transferred to 500mL volumetric flask, dilute to the mark with water and mix. This solution 1mL 1mg containing antimony. 3.7 Antimony standard solution. Pipette 20.00mL antimony standard stock solution (3.6) in 200mL volumetric flask, was added 40mL of hydrochloric acid (3.1), 10mL tartaric acid solution (3.5), dilute to the mark and mix. This solution 1mL containing 100μg antimony.

4 Instrument

Atomic absorption spectrometer, with antimony hollow cathode lamp. Under optimum working conditions, who can achieve the following index value can be used. Sensitivity. antimony characteristic concentration should not exceed 0.30μg/mL. Precision. measure 10 times the absorbance of the highest concentration of the standard solution, the standard deviation should not exceed the average absorbance of 1.0%, with the most Low concentrations of the standard solution (not a "zero" concentration of the solution) absorbance measured 10 times, and the standard deviation is not more than the mean absorbance of the highest concentration of the standard 0.5% luminosity. Linear curve. The curve is divided into five sections according to concentration, than the difference between the absorbance of the absorbance values of the highest and the lowest segment section shall not Less than 0.7. ......
