摘要:

 以红外光谱法为主要手段,原位“跟踪”测定铁(Ⅲ)与乙二酸形成的配合物Na3Fe(C2O4)3•5H2O的热解过程,分析了气、固相热解产物,并以色谱分析、差热-热重分析和X-射线粉末衍射法定性、定量地验证其结果,测定了该配合物的快原子的轰击质谱,提出了断裂规律,铁的二元羧酸配合物的质谱尚属首见.

Abstract:

The thermal decomposition process of iron trisoxalato complex has been investigated by InSitu IR spectroscopy. The Products in gaseous and solid phases were analyzed and verified by gas chromatographic analysis (GC), differential thermal analysis (DTA), thermogravimetric analysis (TGA) and high temperature X-ray powder diffraction (HXRD) as well. The Fast Atom Bombaxdment (FAB) Mass Spectra of title complex were detected.

Key words: In Situ IR spectroscopy, Thermal decomposition, DTA-TGA, FAB-Mass spectra
