Abstract:

Objective: The paper is to innovatively investitgate the application of non-aqueous phase chemical vapor generation
(CVG)in atomic fluorescence spectrometry(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.

Key words: non-aqueous phase chemical vapor generation, atomic fluorescence spectrometry, elemental analysis
