Scope
This part of GB/T 17414 specifies the method for determining the amount of beryllium in beryllium ores by the Elliott's reagent R photometry method.
This part is applicable to beryllium ores, and also to the determination of low-concentration beryllium in lithium, rubidium, cesium ores, and tantalum and niobium ores.
Measurement range: 0.0001% to 1.0% (mass fraction) of beryllium (calculated as beryllium oxide).
