摘要
Abstract
To determine trace thallium in iron ore,the iron ore sample was dissolved with aqua regia.Subsequently,ultra-low content thallium in the solution was extracted and enriched using the organic solvent 4-methyl-2-pentanone,followed by quantitative determination via Induc-tively Coupled Plasma Optical Emission Spectrometry(ICP-OES).The results indicate a linear correlation coefficient of 0.9995,a detection limit of 0.26 μg/g,and an RSD≤7%(n=10).The precision and accuracy of the method meet the requirements of GB/T 6730.81-2020.关键词
