Abstract: | In this paper,the vaporization behaviors of refractory elements (Boron,Chromium,Molybdenum and Silicon)in graphite furnace ETV-ICP-AES have been investigated,and a polytetrafluoroethylene slurry was used as chemical modifier to improve the vaporization of the refractory elements. The factors which influenced the fluorination vaporization process were systematically explored, and a proper vaporization mechanism was proposed. |

Keywords: | refractory elements polytetrafluoroethylene electrothermal vaporization plasma spectrometry vaporization mechanism. |
