This section applies to the determination of high purity tin antimony content. Measurement range. ~ 0.00003% 0.00015%.2 Method summaryPlus 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 ReagentsUnless 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). Weigh 10g sodium nitrite dissolved in 100mL of water, and mix. 3.10 urea saturated solution. 50mL urea was dissolved in hot water, until the urea has not dissolved. 3.11 malachite green solution (1g/L). Weigh 0.1g of malachite green dissolved in 100mL of water, filtered used. 3.12 Antimony standard stock solution. Weigh 0.1000g antimony (wSb≥99.999%) a 50mL beaker, add 20mL sulfuric acid (3.3), heated and dissolved, remove the cooled to room temperature and transferred to 1000mL volumetric flask, dilute sulfuric acid (3.7) to the mark and mix. This solution 1mL antimony-containing 100μg. 3.13 Antimony standard solution. Pipette 10.00mL antimony standard stock solution (3.12), in 100mL volumetric flask, dilute sulfuric acid (3.7) to Volume, and mix.
