A　nanocluster　film　of　Pd-Fe　oxide　layers　was　deposited　on　a　glassy　carbon　electrode　(GCE)　by　continuous　cyclic　scanning　in　a　PdCl2　and　FeCl3　bath.　The　scanning　electron　micrograph　(SEM)　demonstrates　that　the　films　are　uniform　and　the　nanoclusters　are　homogeneously　distributed　on　the　GCE　surface.　The　characterization　of　the　surface　structure　is　discussed　based　on　XPS　techniques.　The　electrochemical　behavior　of　nitrite　on　the　Pd-Fe/GC　modified　electrode　is　investigated.　It　is　found　that　this　modified　electrode　shows　fast　and　substantial　catalytic　ability　towards　the　oxidation　of　nitrite　anions.　This　is　possible　due　to　the　synergetic　effect　of　Pd-Fe　as　opposed　to　that　of　a　pure　Pd　or　pure　Fe-modified　electrode.　The　detection　limit　is　found　to　be　2　x　10(-6)　M,　and　the　linear　concentration　range　is　6　x　10(-6)-5　x　10(-3)　M.　Possible　interference　from　several　common　ions　is　tested.　The　method　was　successfully　applied　to　the　detection　of　nitrite　in　real　samples.
