Liquid-phase microextraction combined with graphite furnace atomic absorption spectrometry: A review
چکیده انگلیسی


• We review the LPME-GFAAS combination in a comprehensive way.
• A brief description of main LPME modes is included.
• Effect of experimental parameters in the performance of LPME-GFAAS is discussed.
• Main applications for trace element analysis and speciation are reviewed.

An overview of the combination of liquid-phase microextraction (LPME) techniques with graphite furnace atomic absorption spectrometry (GFAAS) is reported herein. The high sensitivity of GFAAS is significantly enhanced by its association with a variety of miniaturized solvent extraction approaches. LPME-GFAAS thus represents a powerful combination for determination of metals, metalloids and organometallic compounds at (ultra)trace level. Different LPME modes used with GFAAS are briefly described, and the experimental parameters that show an impact in those microextraction processes are discussed. Special attention is paid to those parameters affecting GFAAS analysis. Main issues found when coupling LPME and GFAAS, as well as those strategies reported in the literature to solve them, are summarized. Relevant applications published on the topic so far are included.
