1 Scope

This part of YS/T 775 specifies the determination of arsenic, copper and selenium content in lead anode mud. This part is applicable to the determination of arsenic, copper and selenium in lead anode mud. Determination range. arsenic. 0.10% ~ 2.00%, copper. 1.00% ~ 5.00%, selenium. 0.10% to 4.00%.

2 method summary

The sample was dissolved in nitric acid in the presence of tartaric acid. The inductively coupled plasma emission spectra were used at the recommended wavelength and instrument operating conditions Direct Determination of Arsenic, Copper and Selenium by.

3 reagent

Unless otherwise stated, only the reagents identified as analytical reagents and distilled or deionized water or comparable purity were used in the analysis. 3.1 Hydrochloric acid (ρ = 1.19 g/mL). 3.2 nitric acid (ρ = 1.42 g/mL). 3.3 Hydrochloric acid (1 1). 3.4 nitric acid (1 1). 3.5 Hydrochloric acid (5 95). 3.6 tartaric acid solution (200g/L). 3.7 copper standard solution. Weigh 1.0000g metal copper (wCu ≥ 99.99%), placed in a 300mL beaker, add 20mL nitric acid (3.2) Dissolve at low temperature, remove the nitrogen oxide by heating, remove and cool, move into a 1000mL volumetric flask, add 50mL nitric acid (3.4), dilute with water To the scale, mix. 1 mL of this solution contains 1 mg of copper. 3.8 arsenic standard solution. Weigh 1.3203g arsenic trioxide (wAs2O3 ≥ 99.99%, pre-drying at 100 ℃ ~ 105 ℃ 1h, placed in Dried in a desiccator, cooled to room temperature), placed in a 300 mL beaker, 20 mL of sodium hydroxide solution (100 g/L) was added, Solution, diluted with water to 100mL, add 2 drops of phenolphthalein, nitric acid (3.4) neutral and neutral, and excessive 40mL, into the 1000mL volumetric flask , Diluted with water to the mark, mix well. This solution 1mL containing 1mg arsenic. 3.9 Selenium standard solution. Weigh 1.0000 g selenium (wSe≥99.99%) In a 100 mL beaker, add 30 mL of nitric acid (3.4) in a water bath Dissolved in the heating, decomposition completely into the 1000mL volumetric flask, add 50mL nitric acid (3.4), diluted with water to the mark, mix. this Solution 1mL containing 1mg selenium. 3.10 argon (wAr ≥ 99.995%).
