Herein, a novel sample derivatization and introduction system based on electrochemical generation of palladium volatile species -PdVS- have been developed for determination of Pd by pyrolytic graphite-coated furnace atomic absorption spectrometry. PdVS are produced in the cathode chamber of a home-made electrochemical vapor generation cell in which a tungsten-inert gas -TIG- welding electrode and Sn-II- were served as the cathode and the enhancement reagent, respectively. The produced PdVS were transferred into a pyrolytic coated graphite furnace by a stream of argon carrier gas where they are trapped and atomized. Plackett–Burman experimental design was used to screen the influential experimental parameters. The effect of significant influential parameters on the method sensitivity were evaluated and optimized. Under optimum operating conditions, the calibration curve for Pd was constructed and showed to be linear in the concentration range of 7.5 to 110 ng L-1 of Pd. Detection -3sb/m- and quantification -10sb/m- limits of the proposed method were evaluated using 10 blank samples and found to be 2.1 ng L-1 and 7.1 ng L-1, respectively. The relative standard deviation -n=7, at 50 ng L-1 concentration level- was 5%. The accuracy of the proposed method was checked by analysing two different certified reference materials which yield the recoveries of 105% and 81% for Pd.
