1 Scope

This section YS/T 981 specifies the method for determination of high-purity indium tin content. This section applies to the determination of 99.9999% purity Indium tin content. Determination range 5 × 10-5% ~ 2 × 10-4%.

2 Method summary

Sample with sulfuric and nitric acid dissolution, heated to remove excess nitrate in 1.2mol/L sulfuric acid solution, tin (Ⅳ) and Phenylfluorone - bromo ten Cetyl trimethylamine colored complex produced, measured at the wavelength of 510nm absorbance. Antimony, iron ion interference, by the addition of tartaric acid, Ascorbic acid and potassium permanganate to eliminate. Chromogenic solution containing 1g if indium, 2μg copper, cadmium, zinc, aluminum, magnesium, silicon, selenium, tellurium, calcium, lead, antimony, 1μg and 10μg iron arsenic, thallium is not It will interfere with the determination of tin.

3 Reagents
