H(TPM)螯合剂(三氟乙酰基特戊酰基甲烷)用于无机物气相色谱分析,目前报道较多的是该螯合物的分离研究。其定量应用有Sokolov等人发表的聚乙烯中微量铝的测定(灵敏度为0.25ppm)。鉴于H(TPM)鳌合剂结构的特点,本文用Cr(TPM)_3对痕量铬进行了定量分析考察,可以看出:Cr(TPM)_3螯合物具有良好的挥发性和热稳 H (TPM) chelating agent (trifluoroacetylpivaloylmethane) is used for gas chromatographic analysis of inorganic compounds. Up to now, more studies on the separation of the chelates have been reported. Its quantitative application of Sokolov et al. Published in the determination of trace aluminum in polyethylene (sensitivity of 0.25ppm). In view of the characteristics of the chelating agent H (TPM), the quantitative analysis of trace chromium with Cr (TPM) 3 was carried out. It can be seen that Cr (TPM) 3 chelate has good volatility and thermal stability
