Book excerpt: This Part of YS/T 254 specifies the method for determining the content of beryllium oxide in beryllium concentrate and beryl. This Part is applicable to the determination of beryllium oxide in beryllium concentrate and beryl. The determination range is 6.00%~14.00%. 2 Method summary The test material is melted with potassium hydrofluoride. Beryllium is converted into beryllium fluoride salt. After sulfuric acid fumes and melts, it is converted into beryllium sulfate. Leach with water. Acidify with hydrochloric acid. Use hydrogen peroxide and disodium ethylenediaminetetraacetate to complex impurity elements. In the presence of ammonium acetate, diammonium hydrogen phosphate is used to precipitate beryllium twice at a pH value of 5.2~5.8. The precipitate is burned into beryllium pyrophosphate at 1000??C. Weigh to constant. 3 Reagents 3.1 Potassium hydrofluoride. 3.2 Sulfuric acid (??1.84 g/mL). 3.3 Hydrochloric acid (??1.19 g/mL). 3.4 Hydrogen peroxide (??1.10 g/mL). 3.5 Ammonia (??0.90 g/mL). 3.6 Hydrochloric acid solution (1+3). 3.7 Ammonia (1+1). 3.8 Diammonium hydrogen phosphate solution (132.5 g/L): Weigh 132.5 g of diammonium hydrogen phosphate.
