Özet:

 

A method was developed for preconcentration of cadmium with  zinc-piperazinedithiocarbamate (ZnPDC) in edible oils and its  determination by flame atomic absorption spectrometer (FAAS).  The  preconcentration method is based on the adsorption of the Cd(II) on to  ZnPDC and the elution of them with mercury(II) nitrate.  The accuracy  of the method was tested with standard reference material (CONOSTAN  S-21) and Cd added samples.  Under optimum conditions, the recovery  and the detection limit for cadmium were 99.67% (\pm 0.67) and 0.028  mg/L, respectively.  The calibration curve was linear over the  concentration range 0.1-3.0 mg/L (r2 = 0.9979).  The proposed method  was applied to the oil standard and commercial edible oils.
