摘要： 本文应用电感耦合等离子体-原子发射光谱法同时测定了部份鸟蛋中某些元素的正常浓度及其分布值。对最佳实验参数进行了选择,研究了共存元素的干扰影响,对不同的试样分解方法进行了比较。方法的检出限分别为0.0029至0.88μg/ml;相对标准偏差为1.3-4.6%(n=10);回收率在90-115%范围。结果表明,本法对生物试样的分析具有灵敏、准确、简便、低水平干扰和多元素同时测定的优点。

Abstract: A method for the determination of Ca, Na, Mg, P, Fe, Al, Cu, Mn, Cr and Zn in the bird eggs by using ICP-AESis described in this paper. The optimum experimental conditions of ICPdischarge were selected; the effects of coexistent elements(Ca, Na, Mg) on line intensities of the analyte and the methods of sample digestion were discussed. The normal concentrations and their contributions in the eggs of Passer montanus saturatus, Ardeola bacchus, Egretta garzetta, nycticorax nycticorax, Pigeon and Hen were also reported. Under experimental conditions the detection limits for the analyte are 0.0029-2.5μg/ml, the relative standard deviations are in the range of 1.3 to 4.6%, and the recoveries of the method are 90-115%.
