摘要: 采用硝酸-高氯酸对江西赣南8个县所产的脐橙样品进行消解,电感耦合等离子体原子发射光谱法(ICP-AES)同时测定试样中Al、As、Ba、B、Ca、Co、Cr、Cu、Fe、K、Li、Mg、Mn、Ni、P、Pb、Zn、Be、Cd、Se、Sr、La、Ce、Y、Sm、Lu等元素的含量。该法的相对标准偏差为0.42%~4.51%,加标回收率为87.7%~114.1%。实验结果表明:脐橙中含有丰富的K、Ca、P和Mg,不同县所产的脐橙各种微量元素含量存在一定差异。

Abstract: A method for the simultaneous determination of trace elements Al,As,Ba,B,Ca,Co,Cr,Cu,Fe,K,Li,Mg,Mn,Ni,P,Pb,Zn,Be,Cd,Se,Sr,La,Ce,Y,Sm and Lu in navel orange after HNO3-HClO4 digestion by ICP-AES was established.The recoveries of spiked samples are between 87.7%and 114.1%,and the RSD(n=3) is in the range of 0.42% to 4.51%.It was found that navel orange is rich in K,Ca,P and Mg and the contents of trace elements in navel oranges from different counties are different.

Key words: ICP-AES, navel orange, trace elements
