| 摘 要： | 小麦是中国北方人的主要粮食作物,小麦中含有大量的对人体有益的微量元素,查明这些微量元素的含量对于人体健康具有非常重要的意义。电感耦合等离子体（ICP）测试微量元素具有灵敏度高的特点。该文利用ICP的特点,将小麦硝化分解后,测试小麦中的微量元素,使用美国生产Optima 2100 DV型电感耦合等离子体发射光谱仪,对小麦中人体有益的微量元素硼、铁、钙、镁及重金属污染指标铜、铅、锌进行测试,该方法具有样品的加标回收率和RSD较好,分析速度快、分析结果准确可靠的特点。

| Abstract: | Wheat is the major food in northern China.It includes many trace elements which are good to human body.Inductively Coupled Plasma（ICP） has a high sensitive feature in testing trace elements.By using this feature of ICP,the content of the trace elements in wheat are tested after decomposed the wheat by nitrating.By using American production Optima 2100 DV-inductively coupled plasma atomic emission spectrometry,the beneficial elements in the wheat,such as boron,iron,calcium,magnesium,and heavy metal pollution index,such as copper,lead and zinc are tested.This method has the characteristics of good spike recovery rate,good RSD rate,rapid accurate and reliable results of testing samples.This method has been used in laboratory test,and has good economic and social benefits.It can expected to use in many fields. |
