1 Scope

YS/T of the provisions of section 36 of the method for the determination of high purity tin, antimony content. This section applies to the determination of high purity tin antimony content. Measurement range. ~ 0.00003% 0.00015%.

2 Method summary

Plus a small amount of sample was dissolved in nitric acid to sulfuric acid. Complex anions with malachite green in hydrochloric acid medium antimony generate green complex with benzene Extraction, spectrophotometer absorbance measured at a wavelength of 635nm.

3 Reagents

Unless otherwise indicated in the analysis using recognized as excellent pure reagents and distilled or deionized water or equivalent purity. Laboratory Are fully cleaned thoroughly with water after soaking in a vessel with a nitric acid solution (119). 3.1 hydrochloric acid (ρ = 1.19g/mL). 3.2 nitric acid (ρ = 1.43g/mL). 3.3 sulfate (ρ = 1.84g/mL). 3.4 benzene, AR. 3.5 hydrochloride (21). 3.6 sulfate (11). 3.7 sulfate (19). 3.8 tin dichloride (100g/L). Weigh 1.0g tin dichloride, dissolved in 5mL hot hydrochloric acid (3.1) was added 5mL water, and mix. Active Now equipped. 3.9 sodium nitrite solution (100g/L).
