摘 要:目的:创新性地开展非水相(non-aqueous phase)化学蒸气发生(CVG)在原子荧光光谱分析(AFS)中的应用研究。方法:研究适用于该体系的元素种类、非水相介质种类并优化实验条件,建立分析性能指标体系。结果:目前已成功实现了汞(Hg)、砷(As)、锑(Sb)、铋(Bi)、镉(Cd)、锡(Sn)、碲(Te)7种元素通过不同的萃取方法将其由水相转移到非水相介质并在非水相CVG-AFS体系中的分析测定,且大部分元素分析性能良好。结论:非水相CVG-AFS技术具有较好的可行性和分析性能,该研究工作为后期非水相CVG技术应用于其他仪器分析方法提供了很好的研究基础。Objective: The paper is to innovatively investitgate the application of non-aqueous phase chemical vapor generation (CVG) in atomic fluorescence spectrometlT (AFS). Methods: The types of elements and non-aqueous media suitable for the system were studied, and the experimental conditions were optimized, and the analytical performance index system was established. Results: Seven elements including mercury (Hg), arsenic (As), antimony (Sb), bismuth (Bi), cadmium (Cd), stannum (Sn) and tellurium (Te) had been successfully determined in non-aqueous phase CVG-AFS system after transferring from solution to non-aqueous phase medium via different extraction methods, with good analytical performance for large part of the elements. Conclusion: Non-aqueous phase CVG-AFS technology has good feasibility and analytical performance. This work provides a good basis for the later application of non-aqueous phase CVG technology in other instrumental analysis methods.
