Grade: ar
Content: ≥ 99.5%
Chloride: ≤ 0.005%
Sulfate: ≤ 0.005%
Water insoluble matter: ≤ 0.005%
Sodium: ≤ 0.02%
Physicochemical properties : yellow crystal or particle. Slightly weathered. Water loss begins at 60 ℃ and becomes anhydrous at 100 ℃. Soluble in 5 parts of water, soluble in acetone, insoluble in ethanol and ether. Its solution is easy to deteriorate in light and air, and it will not be mixed with hot acid and concentrated acid, or the solution will be placed under sunlight to prevent the production of hydrogen cyanide. It contains about 0.2% potassium carbonate in the solution, which can be stable for several months. The relative density (d17) is 1.85. Low toxicity, LD50 (rat, oral) 1600 ~ 3200mg/kg.
Purpose: biochemical research. Ferrites (forming Prussian blue). Determine copper, zinc, palladium, silver and osmium. Test protein and urine. Drop analysis of palladium, osmium and uranium
Save: RT, away from light
