摘要
采用火焰原子吸收光谱法对PTMEG（聚四氢呋喃）中的钠含量的测定进行探讨，并在所选择的条件下进行了加标回收率和精密度试验。回收率在99．15％～101．3％。研究表明该方法简便、快速、准确，并能很好的满足分析要求。
AAS was applied to the analysis of Sodium in the PTMEG. standard addition recovery and precision of the method were investigated. Recoveries of standard addition were 99. 15 % - 101.3 %. The method was applied to the determination of Sodium in the samples with satisfactory results.
