摘　　要：文章建立了一种火焰原子吸收光谱法测定硫酸钡废渣中水溶性钡含量的新方法,采用标准加入法消除了样品的基体干扰,同时利用氯化钾溶液消除电离干扰,提高了水溶性钡测定的准确性。该方法还有效避免了硫酸钡废渣综合利用过程中固化剂对水溶性钡含量的测定影响,为硫酸钡废渣处理工艺的研究提供了坚实的分析技术支持。In this article,a new method for the determination of water-soluble barium in barium sulfate waste residue by flame atomic absorption spectrometry has been developed.The stan⁃dard addition method effectively eliminated the matrix interference of the sample.At the same time,potassium chloride solution was used to eliminate the ionization interference.This method greatly improved the accuracy of the determination of water-soluble barium.The method also effectively avoids the influence of curing agent on the determination of water-soluble barium content in the comprehensive utilization process of barium sulfate waste slag,and provides a analysis technical support for the study of barium sulfate waste slag treatment technology.
