“…Recently we have reported the modification of Al substrate with metallic palladium particles (Pd-Al electrode) (Pournaghi-Azar and Dastangoo, 2004). The Pd-Al modified electrode was used as an effective electrode substrate for immobilization of Prussian blue (PournaghiAzar and Dastangoo, 2004;Pournaghi-Azar and Saadatirad, 2008;Pournaghi-Azar and Ahour, 2008) for preparation of the new modified electrodes. In our previous work we have described electrochemical or electroless preparation of the uranyl hexacyanoferrate (K 2 UO 2 [Fe(CN) 6 )] film on the bare and Pd-Al electrode (Pournaghi-Azar et al, 2009).…”
