1 Scope

This section provides the determination of gallium zinc content. This section applies to the determination of zinc content in gallium. Measurement range. 0.0005% to 0.020%.

2 Method summary

Sample decomposition with nitric acid and hydrochloric acid. Hydrochloric acid and nitric acid to get rid of. 7mol L hydrochloric acid solution in/in After isopropyl ether extraction and separation of gallium, in the original Sub absorption spectrophotometer at a wavelength of 213.9nm, air - acetylene flame measured zinc.

3 Reagents

3.1 nitric acid, pure class distinctions (ρ1.42g/cm 3). 3.2 hydrochloric acid, pure class distinctions (ρ1.19g/cm 3). 3.3 hydrochloric acid (10 + 7). 3.4 isopropyl ether. in a separatory funnel and washed first with a solution of hydroxylamine hydrochloride oscillation (100g/L) or ferrous ammonium sulfate solution (200g/L) was removed through Oxide, and then transferred to a distillation flask, on a water bath at 80 ℃ purified by distillation, collecting fractions of 67 ℃ ~ 69 ℃. Then hydrochloric acid (3.2) saturated. 3.5 standard zinc stock solution. Weigh 1.0000g spectra of pure zinc [(Zn) ≥99.99%] was dissolved in 50mL of hydrochloric acid (1 + 1). cool down, Water moved into 1000mL volumetric flask, dilute to volume, and mix. This solution 1mL containing 1.0mg zinc. 3.6 Zinc standard solution. Pipette 50.00mL standard zinc stock solution (3.5), placed in 500mL flask, diluted with water to the mark. mix Uniform, 1mL solution containing 100μg zinc.

4 Instrument

Atomic absorption photometer.

5 Sample
