Scope
This standard specifies the principles, reagents and solutions, instruments and equipment, analytical procedures, result calculation, and precision for determining lead in grains using a rare acid extraction and graphite furnace atomic absorption method. This standard is applicable to the determination of lead in raw grains such as wheat, corn, and rice, as well as milled products. The detection limit for lead in this standard is 0.016 mg/kg, and the quantification limit is 0.054 mg/kg.
