1963年国外分析化学家对用气体色层法分析金属的工作取得一些进展。据说这种方法很迅速、相当灵敏、所需仪器设备叉较简单。他们发现有些金属鳌合物可以挥发而且稳定,能在比较低的温度下通过分离柱而不分解,于是气体色层法在金属分析中的应用才引起了重视。为了寻找易于挥发的螯合物,他们选定就三氟乙酰丙酮盐和六氟乙酰丙酮盐进行实验。结果表明,这 In 1963, foreign analysts made some progress in the analysis of metals by gas chromatography. It is said that this method is very fast, very sensitive, the required equipment fork more simple. They found that some metal chelates can volatilize and stabilize, and can pass through the separation column without decomposing at a relatively low temperature. Therefore, the application of gas chromatography in metal analysis has attracted much attention. In an effort to find chelates that are easily volatile, they chose to experiment with trifluoroacetylacetonate and hexafluoroacetylacetonate. The results show that this
