This standard specifies a general method for the determination of metal impurities in chemical reagents by atomic absorption spectroscopy (AAS) after solvent extraction, especially for the determination of metal impurities with poor sensitivity or interference. The standard specifies the method principle, reagent requirements, instrument configuration and determination steps in detail, providing standard operating instructions for the accurate analysis of trace metal impurities in chemical reagents.
