Abstract
In this research, an environmental friendly extraction method based on vortex-assisted liquid-phase microextraction and the solidified deep eutectic solvent (VALPME-SDES) has been developed for the determination of Pb, Cd, Cu, As, and Hg in tea prior to their analysis by graphite furnace atomic absorption spectrometry (GFAAS). A new deep eutectic solvent consisting of 1-decyl-3-methylimidazolium chloride and n-butanoic acid was used as an extraction solvent, yielding the advantages of material stability, low density, and a suitable freezing point near room temperature. The accuracy of the proposed procedure was also assessed by determining the concentration of the studied metal ions in a certified reference material for Green Tea (GBW 10052).
