Abstract: In this paper, a novel micro drop solvent extraction technique jonied with low temperature ETV-ICP-AES for ultra trace element analysis is reported.The apparatus of micro drop solvent extraction was designed, and preliminary investigation was made for the extraction of ultra trace La by a micro drop of 0.05mol/L PMBP-benzene(2μL).It was found that 500-fold concentration of ultra-trace La in 1m Lsolution was achieved in 0.2 mLof glass chamber by a single micro drop of PMBP-benzene suspended on the tip of a 10μLof microsyringe.The future development of micro drop solvent extraction technique in atomic spectrometry was briefly discussed.

Key words: Micro drop solvent extraction, Low temperature electrothermal vaporization, ICP-AES, Ultra trace analysis
