GB/T 9735-2008
ActiveChemical reagent - General method for the determination of heavy metals
化学试剂 重金属测定通用方法
Application Summary AI generated
This standard specifies a general method for determining the content of heavy metals (such as lead, copper, and zinc) in chemical reagents, primarily using visual colorimetry or spectrophotometry. It is applied in the quality control and testing of laboratory chemical reagents to ensure they meet purity specifications for use in analytical chemistry, pharmaceutical production, and industrial manufacturing. The method is commonly used by reagent manufacturers, testing laboratories, and regulatory bodies to verify that heavy metal impurities remain below permissible limits.
