赣南柿子中钙、镁、铁、铜、锰和锌的测定

Determination of Ca,Mg,Fe,Cu,Mn and Zn in Persimmon from Gannan

测定赣南柿子中钙、镁、铁、铜、锰、锌的含量,为进一步开发提供科学依据。采用微波消解-原子吸收光谱法测定赣南柿子中微量元素Ca、Mg、Fe、Cu、Mn、Zn的含量。赣南柿子中Ca、Mg、Fe、Cu、Mn、Zn的含量分别为2097.286、587.481、214.762、909.297、17.159、28.658μg.g-1,回收率为96.53%—113.29%。赣南柿子含有丰富的金属元素,以Ca、Cu含量较高,Zn、Mn含量较低,Mg、Fe含量居中。

The contents of traces elements Ca,Mg,Fe,Cu,Mn,Zn in persimmon from Gannan were determined to provide the basis for further development by flame atomic absorption spectroscopy（FAAS） with microwave digestion.The contents of six trace elements Ca,Mg,Fe,Cu,Mn,Zn in persimmon were 2097.286,587.481,214.762,909.297,17.159,28.658μg·g-1.The recoveries of this method were between 96.53% and 113.29%.Persimmons from Gannan had plentiful metal elements,and the contents of Ca and Cu were higher,the contents of Zn and Mn were lower,while the contents of the Mg and Fe were centered.
