电感耦合等离子体—原子发射光谱法测定动物内脏中的痕量稀土元素

电感耦合等离子体—原子发射光谱法测定动物内脏中的痕量稀土元素 THE DETERMINATION OF TRACE AMOUNTS OF RARE EARTHS IN ANIMAL TISSUE BY ICP SPECTROGRAPHIC METHOD 江祖成 first-author 廖振环 乐晓春 <正> 电感耦合等离子体——原子发射光谱分析法（ICP—AES）在矿石、钢铁、高纯稀土和海水中痕量稀土元素的测定中的应用日益广泛[1-3]。但迄今为止,关于应用这一分析技术测定生物试样中痕量稀土元素的报导尚不多见。为了研究稀土元素在动物体内的富集与分布,本文提出了同时测定白鼠内脏中痕量稀土元素La、Ce、Pr、Nd、Sm和Y的分析方法。本文对影响ICP放电的几个主要因素（功率、载气流量和观察高度）作了合理选择;对试样的分解方法（干法和湿法）进行了试验相比较;对干扰元素（Na,Ca和Cs）的影 A method on the determination of trace La, Ce, Pr,Nd, Smand Y in animal tissue by ICP-AES has been described. The samples are decomposed by using a chemical process prior to analysis, and the comparison of different decomposition methods was made in this paper. The detection limits for the analyte are between 0.00x—0.000x μg/ml; the precisions are in the range of 1 to2%; and the recoveries for above elements are between 92—109%。 1984-02-01 2021-04-01 2
