Abstract

 In this study, a novel vortex-assisted liquid-liquid microextraction based on solidification of a floating organic droplet (VALLME-SFO) was proposed for the microextraction of Pd(II) before its determination by flame atomic absorption spectrometry. A central composite design was used to find the optimum conditions for the preconcentration procedure through response surface methodology. Five variables, including type and volume of extraction solvent, solution pH, ligand concentration, and duration of vortex exposure, were investigated. Under optimum conditions, pH=7, 1. 5 ml of 2-mercaptobenzimidazole 3 mM, 40 μ l of 1-Undecanol, a detection, and 5 min vortex, detection limit 3. 3 μ g/l and quantitation limit 11 μ g/l with the relative standard deviation 2. 4% was achieved. The recoveries of the analytes in Karadj river samples were in the range of 96– 104 %. Analysis of variance (ANOVA) was used to show lack of interferences in the matrix of real samples.
