傅立叶变换离子回旋共振质谱用于金属加工助剂中的成分分析

金属加工助剂是金属加工生产过程中必不可少的化工产品,其组成复杂,易形成螯合物干扰成分分析。该文利用傅立叶变换离子回旋共振质谱(Fourier transform ion cyclotron resonance mass spectrometry,FT-ICR MS)技术的高分辨性能,结合电感耦合等离子体质谱(ICP-MS)、红外光谱(IR)和核磁共振谱(NMR)对一种含未知成分的金属加工助剂进行成分分析。结果表明,该金属加工助剂中含有柠檬酸钠、乙二胺四乙酸(EDTA)与金属铋螯合物。该方法简便、准确,适用于含有金属螯合物的金属加工助剂成分的快速鉴定。

Analysis of Compositions in Metal Processing Additive by Fourier Transform Ion Cyclotron Resonance Mass Spectrometry

A method was developed for the analysis of unkwown compositions in a metal processing additive by Fourier transform ion cyclotron resonance mass spectrometry(FT-ICR MS) combined with nuclear magnetic resonance(NMR),infrared spectroscopy(IR) and inductively coupled plasma mass spectrometry(ICP-MS).Metal processing additives with complex compositions are essential chemical products in metal production.They could easily form the chelates interfering analysis.In this paper,the metal processing additive sample was analyzed by FT-ICR MS combined with NMR,IR and ICP-MS,and sodium citrate and EDTA-Bi chelate were detected.Results showed that the method was simple and accurate,and could be applied in the rapid identification of metal processing additives containing metal chelates.
