摘  要:
采用微波消解和火焰原子吸收光谱法对汉中市4个县区5份银杏叶片样品中的Fe、Mn、Zn、Cu的含量进行测定。结果表明:5个银杏叶片样品中4种微量元素含量(μg/g)依次分别是陕西理工学院校园Fe 365.7、Mn 24.3、Zn 13.6、Cu 8.7;汉台区Fe 283.1、Mn 20.7、Zn 10.2、Cu9.4;城固县Fe 395.0、Mn 30.5、Zn 19.3、Cu 18.0;南郑县Fe 194.4、Mn 25.0、Zn 13.0、Cu 7.7;勉县Fe 214.4、Mn 27.0、Zn 12.1、Cu 8.4;检出限(μg/mL)Fe 0.015、Mn 0.019、Zn 0.0062、Cu 0.006;回收率92%~110%。同一银杏叶片样品中各元素含量Fe>Mn>Zn>Cu,其中城固县样品中各微量元素的含量普遍较高。

摘  要:
The content of Fe,Mn,Zn and Cu in Ginkgo leaves were determined by microwave digestion-flame atomic absorption spectrometry.In this experiment,the content of four microelements including Fe,Mn,Zn and Cu(μg/g) was 365.7,24.3,13.6,8.7 respectively in the sample collected from campus of Shaanxi University of Technology;283.1,20.7,10.2,9.4 respectively in Hantai;395.0,30.5,19.3,18.0 respectively in Chenggu;194.4,25.0,13.0,7.7 respectively in Nanzheng and 194.4,27.0,12.1,8.4 respectively in Mianxian;the limit of determination was Fe 0.015,Mn 0.019,Zn 0.0062 and Cu 0.006 μg/mL;the rate of recovery was 92%~110%.The content of four elements was Fe>Mn>Zn>Cu in the same samples,and the content was higher in Chenggu than others.
