This standard specifies methods for the determination of arsenic and bismuth in copper concentrates, including hydride generation - Atomic fluorescence spectrometry, AFS, potassium bromate Titrimetric method and silver diethyldithioamino formic acid Spectrophotometric method, spectrophotometry. The applicable range is 0.010% to 2.00% arsenic content and 0.010% to 0.70% bismuth content. Hydride generation - Atomic fluorescence spectrometry, AFS dissolves the sample through nitric acid and sulfuric acid, and separates arsenic and bismuth in ammonia solution, and then determines its content through a hydride generator and Atomic Fluorescence Spectrometer (AFS). The standard also covers the specific steps and reagent requirements for both Miscellaneous methods to ensure accurate determination of arsenic and bismuth in copper concentrates.
