Scope
This part of GB/T 17415 specifies the method for determining the amount of tantalum in tantalum and niobium ores by the photometric method of butylrhodamine B.
This part is applicable to tantalum and niobium ores, and also to the determination of the amount of tantalum in lithium, rubidium, and cesium ores.
Measurement range: 0.005 0% to 1.0% (mass fraction) of tantalum content (calculated as tantalum pentoxide).
