摘要

目的: 测定蒙古扁桃种仁中Ca

Sn等9种微量元素含量。方法: 用湿法消解样品

同时做空白溶液

采用电感耦合等离子发射光谱(ICP-AES)法同时测定9种元素含量。结果: 9种元素线性关系良好

Abstract

Objective:To establish a method for determination of nine elements of Ca

Sn and Pb in the kernels of Prunus mongolica. Method: The samples were digested by nitric acid and perchloric acid. The content of nine elements in the kernels of P. mongolica was determined by ICP-AES

a blank experiment was made at the same time. Result: The results showed that the linear relationship was good and the correlation coefficients were all greater than 0.999

and the detection limits was between 0.000 7-0.089 μg·g-1. The recovery rate of ten elements was between 93% and 110%

and the relative standard deviation was between 0.30% and 1.69%. Conclusion: This method is fast

simple and accurate. It can provide a scientific basis for the comprehensive utilization of resources.
