This part specifies the graphite furnace atomic absorption method for the determination of iron content in industrial acrylonitrile. This section applies to the determination of trace iron in acrylonitrile, the determination range (0.010-1.000) mg/kg. This section is not intended to address all safety issues related to its use. Users are responsible for taking appropriate safety and health measures to ensure compliance with relevant national laws and regulations.
