两种海胆矿质元素的ICP-MS法测定分析
Determination of mineral elements in two kinds of sea urchin by ICP-MS method
摘要
Abstract
Eighteen kinds of mineral elements in sea urchin,Hemicentrotus pulcherrimus and Anthocidaris crassispina,were detected and analyzed by inductively coupled plasma mass spectrometry（ICP-MS）.6Li,45Sc,72Ge,89Y,115In,159Tb,209Bi were selected as the internal standard elements.The matrix effect was compensated and the MS interference was corrected by selecting the suitable isotope of the elements.The experimental conditions were optimized.The samples were digested with HNO3＋HClO4（4：1）.All the detected elements showed a good linear relationship within the working curves,the correlation coefficients were all above 0.9984.The precisions and recoveries were good,the range of recoveries（n=3） was 93.11%～116.91% and the RSDs were all lower than 5%.The results indicated that there were abundant nutritional elements for people in the two kinds of sea urichin.They were all rich in the elements K,Mg,Ca and some trace elements which are beneficial to humans such as Zn,Fe,Cu,V,Mn,Se.This study will provide some useful evidence for the effective exploitation of sea urichin.关键词
