湿法消解-火焰原子吸收光谱法测定黑种草籽中的4种金属元素

Determination of Four Kinds Mental Elements in Fennelflower Seed by Flame Atomic Absorption Spectrometry with Wet Digestion

黑种草籽经湿法消解,用火焰原子吸收光谱法测定Cu、Fe、Mn、Zn的含量。该方法快速、简便、准确,4种金属的回收率为97.85%—101.95%,RSD为0.68%—2.08%,结果表明,黑种草籽中铁、锌元素含量较高。

The contents of copper,iron,manganese and zinc in fennelflower seed were determined by flame atomic absorption spectrometry（FAAS） with wet digestion.The relative standard deviation and recoveries of four mental elements were 0.68%—2.08% and 97.85%—101.95%,respectively.The method is simple,rapid and accurate.The results showed that the contents of iron and zinc in the fennelflower seed were relative high.
