Abstract: The vaporization and transport modes of Be and Cr(Ⅲ) from the graphite tube were studied by using the low temperature vaporization technique combined with ICP-AES. The main factors of influencing the formation of Be and Cr(Ⅲ) acetylacetonates were investigated. It was found that the Be and Cr(Ⅲ)} acetylacetonates were able to vaporize and introduce quantitatively into ICP with good thermal stability and volatility. The chelation reaction between the analyte and acetylacetone should be completed before the sample introduction to avoid the formation of refractory carbide and to eliminate the memory effect.

Key words: Low temperature electrothermal vaporization, Acetylacetone, Chemical modification agent, Be, Cr(Ⅲ)
