火焰原子吸收法测定潮州芡实中的矿质元素

Determination of some minerals in Gorgen fruit with atomic absorp tion spectrometry

用火焰原子吸收光谱法测定了潮州芡实中的K、Na、Ca、Mg、Cu、Zn、Mn、Fe、Ni、Pb、Cd等微量元素 ,为潮州芡实的开发提供了依据。各元素的回收率在 95 %～ 10 5 %。结果表明 ,潮州芡实中富含人体必需的微量元素及大量元素 ,有害元素Pb、Cd等含量较低。

The content of macroelements (Na,K,Ca,and Mg) and mi cr aelements (Fe,Cu,Zn,Mn,Pb,Cd and Ni) in gorgen fruits of Chaozhou was determined with atomic absorption spectrometry.The results showed that there were abundant beneficial mineral elements in the gorgen fruits of Chaozhou ,such as K,Na,Ca,M g,I,Zn and Mn,and lower in Cu,Pb and Cd.
