电感耦合等离子体质谱法测定地质样品中的稀土、钍元素
Determination of Rare Earth and Thorium Elements in Geochemical Samples by Inductively Coupled Plasma Mass Spectrometry
摘要
Abstract
An analysis method is developed based on ICP - MS for the determination of 15 kinds of rare earth (Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) and thorium elements in soil and rock. In order to avoid deviation caused by matrix effect and instrument fluctuation effectively, Rh internal standard solution is introduced in analysis. Accurate isotope is selected to correct mass interference by experimental test and reference materials are tested by comparison. The correlation coefficients of standard curve for all the elements are more than 0. 999 0 and the detection limit of the method is less than 0. 008 9 μg/g. The relative standard deviations are between 0. 87% and 2. 92%.关键词
