Scope

Main technical content: This document specifies the term definitions, method principles, reagents and materials, instruments and equipment, sample preparation, result calculation, method performance, quality assurance, and precautions for the determination of uranium content in zirconium tailings. This document is applicable to the determination of uranium in zirconium tailings waste. If validated, this document can also be applied to the determination of uranium in other metal mine tailings. Note: When the amount of solid waste samples is 0.1 g and the volume of the solution after digestion is 50.0 ml, the measurement range is 0.1 mg/kg to 4000 mg/kg.
