1 Scope

YS/T 1014 This section specifies the method for determination of bismuth trioxide in the amount of bismuth trioxide. This section applies to the determination of bismuth trioxide bismuth trioxide amount measurement range. ≥98.0%.

2 Method summary

Sample dissolved in nitric acid, sodium acetate to adjust the pH value between 1.5 to 1.7, with xylenol orange as indicator, with standard Na2EDTA Titration titration solution, measured the amount of bismuth trioxide.

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 ascorbic acid. 3.2 nitric acid (ρ = 1.42g/mL). 3.3 nitric acid (595). 3.4 thiourea saturated solution. 3.5 tartaric acid solution (200g/L). 3.6 Anhydrous sodium acetate (200g/L). 3.7 Na2EDTA Standard Solution (about 0.020mol/L). 3.7.1 preparation. Weigh 7.60g disodium edetate in 300mL beaker, add water, heat gently to dissolve, cooled to room temperature and transferred to 1000mL volumetric flask, dilute to the mark, mix, place three days after calibration. 3.7.2 Calibration. Weigh 0.197g bismuth (wBi≥99.99%) (accurate to 0.0001g) 5 parts were placed in 500mL beaker triangle , The tartaric acid solution is added 5.0mL (3.5), was added 10mL of nitric acid (3.2), a low temperature around completely dissolved by heating, and evaporated to 5mL, taking Under rinsed with water and dish table Beibi, ascorbic acid was added 0.5g (3.1), 5.0mL saturated solution of thiourea (3.4), 100mL water and shake. With The same below 6.4.2. Along with the calibration blank test. According to equation (1) to calculate the actual concentration Na2EDTA standard titration solution. c = 1000 × m0 (V1-V0) × 208.98 (1) Where. The actual concentration c --- Na2EDTA standard titration solution, expressed in moles per liter (mol/L); m0 --- saying that the quality of the calibration to take bismuth, in grams (g); --- Bismuth molar mass of 208.98 units of grams per mole (g/mol); When V1 --- calibration volume Na2EDTA standard titration titration solution consumed bismuth solution in milliliters (mL); V0 --- the calibration, volume Na2EDTA standard titration solution consumed in the blank titration solution in milliliters (mL). ......
