摘要：

目的：研究貂心与其易混品种鸡心中的人体必需微量元素的种类及其含量差异，为貂心与易混品种鸡心的鉴定提供一种科学的方法。方法：应用电感耦合等离子体原子发射光谱（ICP-AES）法测定经消化后的貂心和鸡心中的微量元素。[JP3]结果：貂心中含有8种微量元素，其中镁(Mg)含量(干重)最高，为685.31 mg/kg[JP]；鸡心中含有9种微量元素，其中钾(K)含量（干重）最高，为11 829.7 mg/g。各种微量元素的检测线为0.4～12.1 μg/L，回收率为92.0%～111.9%，相对标准偏差为0.5%～3.8%，各种微量元素的标准曲线均为R≥0.9 999。结论：貂心与鸡心中所含微量元素的种类、含量及各种元素含量间的比例相差悬殊，可
利用ICP-AES法对二者进行微量元素检测比较和鉴定。

Abstract:

Abstract:Objective To investigate the kinds and contents of trace elements in marten’ s heart and chicken’ s heart (which is easily confused with marten’ s heart),and provide a scientific method to identify them.Methods The various trace elements in marten’ s heart and chicken’s heart were measured by inductively coupled plasma atomic emission spectroscopy（ICP-AES）after they were treated with concentrated nitric acid.Results Eight kinds of trace elements were found in marten’s heart.The magnesium content was 685.31 mg/kg and it was the highest among the detected trace elements.Nine kinds of elements were found in chicken’s heart,but the potassium content was 11 829.7 mg/kg and the highest in it.The detection line of different elements was 0.4-12.1 μg/L,the recovery rate of the method was 92.0%-111.9%,the RSD(n=5) was 0.5%-3.8%,and all R values of the different standard curves were more than 0.999 9.Conclusion There are great differences in kinds,contents and the content ratios of different elements in marten’ s heart and chicken’ s heart. The results suggest that ICP-AES can be used for identifying marten’ s heart and chicken’ s heart.

Key words: marten’s heart;inductively coupled plasma atomic emission spectroscopy;trace element
