The present work describes oxidation of ascorbic acid (AA) at octacyanomolybdate-doped-glutaraldehyde-crosslinked poly-l-lysine (PLL-GA-Mo(CN) 4Γ 8 Γ film modified glassy carbon electrode in 0.1 M H 2 SO 4 . The modified electrode has been successfully prepared by means of electrostatically trapping
A chemically modified electrode constructed by incorporating iron(II) phthalocyanine [Fe(II)Pc] into carbon-paste matrix was used as a sensitive potentiometric sensor for detection of ascorbic acid. The resulting electrode exhibits catalytic properties for the electrooxidation of ascorbic acid, and
