Abstract: In this paper, the vaporization processes of vanadium and titanium in GF-ETV-ICP-AEShave been investigated in detail.By observing and comparing the vaporization behavior of vanadium and titanium in the presence/absence of fluorinating agent, PTFE, together with the results of residues chemical composition analysis after graphite furnace heating cycle, the vaporization mechanisms of vanadium and titanium in graphite furnace have been proposed, and it is verified by the results of thermodynamic calculation.

Key words: Graphite furnace electrothermal vaporization, Vaporization mechanism, Vanadium, Titanium, Polytetrafluoroethylene(PTFE)
