1 Scope
GB/T 14353 provisions of this part of the simultaneous determination by inductively coupled plasma mass spectrometry gallium content of copper ores lead ores and zinc ores,
The amount of indium, thallium content, the amount of tungsten and molybdenum content.
GB/T 14353 apply to this part of the copper ore, inductively coupled lead ores and zinc ores in the amount of gallium, indium amount, the amount of thallium, tungsten and molybdenum content in the amount of
Plasma mass spectrometry.
Measuring range. 0.13μg/g ~ 40μg/g of gallium, 100μg/g of indium 0.01μg/g ~, 0.03μg/g ~ 40μg/g of thallium,
0.08μg/g ~ 150μg/g of tungsten and 0.18μg/g ~ 150μg/g of molybdenum.
The detection limits. gallium 0.042μg/g, indium 0.004μg/g, thallium 0.009μg/g, tungsten 0.026μg/g, molybdenum 0.061μg/g.

Principle 3
Sample nitric acid - hydrofluoric acid - perchloric acid decomposition, aqua regia dissolved salts, polyethylene move 25mL graduated test tube, diluted with water to
Mark and shake. An aliquot of the solution was diluted with nitric acid (397). By inductively coupled plasma as the ion source, the sample solution
Analyte ionization, the resulting sample ions through the mass analyzer and detector to give mass. According to the ion mass to charge ratio of the element count, the use of
Quantitative determination of the calibration curve solution of gallium content, the amount of indium, thallium amount, the amount of tungsten and molybdenum samples.
4 Reagents
Unless otherwise indicated in the analysis are consistent with the use of analytical reagents and GB/T 6682 water analytical laboratory.
4.1 nitric acid (ρ = 1.42g/mL).
4.2 Hydrofluoric acid (ρ = 1.13g/mL). Warning. Toxic and corrosive hydrofluoric acid, the operation should wear gloves corrosion, prevent contact with skin.
4.3 perchloric acid (ρ = 1.68g/mL). Warning. explosive materials, when used carefully!
4.4 hydrochloric acid (ρ = 1.19g/mL).
4.5 aqua regia (hydrochloric acid, nitric acid = 31).
