Abstract

In this study, a new sorbent based on dimethylglyoxim/sodium dodecyl sulfate-immobilized on TEOS-coated magnetic nanoparticles (Fe3O4@SiO2@SDS/DMG) was prepared as a simple, inexpensive, and fast method for pre-concentration and determination of trace amounts of Palladium. In the proposed approach, the analytes retained on the sorbent are effectively eluted with thiourea– HCl solution and the absorbance of analyte was determined by Flame atomic absorption spectrometry. The effects of different parameters on extraction efficiency such as effect of pH, extraction time, type and amount of eluent, and amount of absorbent phase were investigated and optimized by batch procedures. Under the optimum experimental conditions, the preconcentration factor, detection limit, linear range, and relative standard deviation (RSD) of Palladium (II) ions were 250, 0. 49 μ gl-1, 125-3750μ gl-1, and 2. 26 % (for 125μ gl-1, n=6), respectively. Finally, the method was successfully applied to the evaluation of Pd2+ in different environmental water samples.
