1 Scope

This section GB/T 23364 specifies the determination of the amount of chlorine of high purity indium oxide. This section applies to the determination of the amount of chlorine in high purity indium oxide, the measurement range (mass fraction) of 0.025% to 0.80%.

2 Method summary

In chlorine-free environment, the sample was dissolved in nitric acid, ammonia separation matrix indium to eliminate its effects. Chloride in an acidic solution in quantitative substituted sulfur Cyanate mercury thiocyanate ions released thiocyanate ions with an excess of ferric thiocyanate ions generated reddish brown iron compounds in the spectral Absorbance was measured at 460nm wavelength photometer, thereby indirectly measuring the amount of chlorine.

3 Reagents

Unless otherwise stated, only recognized as analytical grade reagents and deionized water or equivalent purity; prepared and stored in a chlorine-free environment Reagents and solutions. 3.1 nitric acid (ρ about 1.42g/mL), pure class distinctions. 3.2 Ammonia (ρ about 0.90g/mL), pure class distinctions. 3.3 nitric acid (1 + 1). 3.4 KCl, reference reagents, after 400 ℃ ~ 450 ℃ burn 30min, and cooled to room temperature in a desiccator. 3.5 ferric nitrate solution (300g/L). Weigh 150g of ferric nitrate, placed in 500mL beaker, add 500mL nitric acid (3.3) is dissolved, Mix well. 3.6 mercury thiocyanate solution (2g/L). Weigh 1g mercuricthiocyanate placed in 500mL anhydrous ethanol, shake, place the filter in brown after 4h Color bottle save. Prior to filtration, was added dropwise nitric acid (3.3) filter paper was washed 5 times with deionized water until neutral. 3.7 Storage chlorine standard solution. Weigh 2.1028g reference potassium chloride (3.4), placed in 250mL beaker, with the right amount of water to dissolve, moved 1000mL volumetric flask, dilute with water to volume, and mix. This solution 1mL 1mg containing chlorine. 3.8 Chlorine Standard Solution A. Pipette 10.00mL chlorine standard stock solution (3.7), placed in 100mL volumetric flask, dilute to the mark with water, Mix well. This solution 1mL containing 100μg chlorine. 3.9 chlorine standard solution B. Pipette 25.00mL chlorine standard solution A (3.8), placed in 100mL volumetric flask, dilute to the mark with water, mix uniform. This solution 1mL containing 25μg chlorine.

4 Instrument

4.1 Spectrophotometer. 4.2 centrifuge.

5 Sample

The specimen should be 105 ℃ ~ 110 ℃ drying 2h, placed in a desiccator to cool to room temperature. Step 6 Analysis 6.1 Sample Table 1 sample was weighed, accurate to 0.0001g.
