Cereals — Determination of cadmium content by graphite furnace atomic absorption spectrometry with diluted nitric acid extraction 谷物.用稀释硝酸萃取石墨炉原子吸收光谱法测定镉含量

发布日期： 2021-12-15

本文件规定了谷物中镉（Cd）的测定方法。
适用于大米、糙米、小麦、玉米经稀硝酸（HNO3）萃取后石墨炉原子吸收光谱法（GFAAS）测定。定量限为0,002？毫克/千克；它是近似的，取决于样品基质以及仪器条件。

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 (HNO3). 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.
