  In this research, a simple and effective method was developed for pre-concentration and determination of palladium ion, based on displacement with Cu(DDTC)2 complex in aqueous samples. This method involves two steps. First, Cu2+ reacts with diethyldithiocarbamate to form Cu(DDTC)2 complex, which is extracted by microfunnel-supported liquid phase microextraction method using n-octanol as extraction solvent. Next, Cu2+ was replaced with Pd2+ to form Pd(DDTC)2in the organic phase and then was measured using flame atomic absorption spectrometry. In order to optimize effective parameters, Box-Behnken design methods were used. Under optimized conditions, enhancement factor (EF), limit of detection (LOD), and relative standard deviation (RSD) (n=8) were obtained 153, 1.22 μg.l-1 and 4.9%, respectively. Finally, this method was successfully used to determine Pd in water samples. Manuscript profile
