1 Scope

This section GB/T 8151 specifies the method for the determination of fluorine content in zinc concentrates. This section applies to the determination of fluorine in the amount of zinc concentrate. Measurement range. 0.050% to 0.50%.

2 Method summary

Sample decomposition of molten potassium hydroxide with water after leaching the melt filter, separating the fluorine and iron, lead elements, then the solution was adjusted with nitric acid Acidity, with citric acid ammonium ionic strength adjustment, the use of electrode potential instrument to a saturated calomel electrode as the reference electrode, fluoride ion-selective electrode Indicator electrode determination of fluorine.

3 Reagents

Unless otherwise indicated, as used in the analysis confirmed that only analytical reagent and distilled water or equivalent purity. 3.1 Potassium hydroxide, pure class distinctions. 3.2 nitric acid (11). 3.3 ammonium citrate solution. Weigh 243g of ammonium citrate, dissolved in about 700mL of water with nitric acid (3.2) adjusted to pH6.0 ~ 6.5, with Diluted with water to 1000mL, and mix. 3.4 fluoro standard stock solution. Weigh 2.2110g pre-dried at 120 ℃ 2h sodium fluoride (excellent pure), was dissolved in water and go 1000mL volumetric flask, constant volume of water, mix, transferred to drying plastic bottles saved. 1mL solution containing 1mg fluorine. 3.5 fluoro standard solution A. Pipette 50.00mL fluoro standard stock solution (3.4) in 500mL volumetric flask, dilute to the mark, mix Uniform, moved into dry plastic bottles. This solution 1mL containing 100μg fluorine. 3.6 fluoro standard solution B. Pipette 50.00mL fluoro standard solution (3.5) in 500mL volumetric flask, dilute to the mark, mix, shift Into dry plastic bottle solution 1mL containing 10μg fluorine. 3.7 bromocresol green indicator. Weigh 0.1g bromocresol green dissolved in 20mL of anhydrous ethanol, dilute with water to 100mL, and mix.

4 Instrument

4.1 FISE. Requires fluorine content in 10-1mol/L ~ 10-5mol/L, the negative electrode potential and the logarithm of the concentration showed a good line Sexual relations. Electrode before use, should be soaked in a solution of sodium fluoride 10-3mol/L activated in 1h, then washed with water to a fluorine-containing little In 10-5mol/L only after the measurement. 4.2 saturated calomel electrode. 4.3 potential measurement instrument. accuracy 0.1mV. 4.4 magnetic stirrer. ......
