【摘要】 建立湿法消解-火焰原子吸收光谱法测定富硒农产品中硒元素质量浓度的方法。采用硝酸-高氯酸（4:1）对样品进行消解处理，利用原子吸收光谱仪进行检测。结果表明，在 2.0～12.0 μg·L^-1质量浓度范围内，吸收强度与浓度呈良好的线性关系，回归方程为 y=0.009 2x+0.010 6,r=0.999 3。该方法操作简便，结果准确，适用于农产品中硒的质量浓度分析。更多还原

【Abstract】 A determination method of selenium in selenium-rich agricultural products by atomic absorption spectrometry with wet digestion was established. The samples were pretreated with nitric acid-perchloric acid （4∶1）, and were determined by AAS. The results showed that the linear regression equation of selenium was y = 0.009 2x + 0.010 6 in the range of 2.0～ 12.0 μg·L^-1, r=0.999 3.The method was simple, accurate and suitable for the analysis of selenium in agricultural products.更多还原
