摘要
本文研究了以邻菲罗啉为金属螯合剂,高氯酸钠为配体,在一定酸度下用1,2-二氯乙烷萃取-火焰原子吸收法测定动物骨骼中微量Cu、Zn、Cd和Fe的条件,并确定了测定方法。方法简单、准确、可靠。元素的检测限分别为:Cu:0.038μg/ml,Zn:0.0042μg/ml,Cd:0.0019μg/ml,Fe:0.02μg/ml,回收率在92.
Trace content of Cu,Zn,Cd and Fe in bones is determined by flame atomic absorption spectrometry after preceding preconcentration using the extraction system O phenanthroline sodium perchlorate/1,2 dichloroethane.Also,the factors of influence were studied.The method was simple,accurate and reliable,The detection limits were Cu:0 038μg/ml,Zn:0 0042μg/ml,Cd:0 0019μg/ml,Fe:0 02μg/ml.The recovery rate was between 92 8 and 105%.
