标准摘要
[中文适用范围]： 本标准规定了谷物中镉（Cd）的测定方法。 适用于大米、糙米、小麦和玉米经稀硝酸（HNO3）提取后采用石墨炉原子吸收光谱（GFAAS）测定。 定量限为0.002 mg/kg；它是近似值，并且取决于样品基质以及仪器条件。 [外文原描述]： This document specifies a method for the determination of cadmium (Cd) in cereals. It is applicable to rice, brown rice, wheat and maize by graphite furnace atomic absorption spectrometry (GFAAS) after extraction with diluted nitric acid (HNO 3 ). The limit of quantification is 0,002 mg/kg; it is approximate and dependent on the sample matrix as well as on the instrument conditions.
