| Abstract: | A polyaniline/polypyrrole (PANI/PPy) polymer film was deposited on a tin oxide coated glass electrode, which was used
to study electrochemical behaviour of furazolidone by cyclic voltammetric method. Two well-defined reduction peaks (c₁ at
-0.358V and c₂ at -0.784V) and one oxidation peak were observed at 0.306 V. The results, compared with that of a glassy
carbon electrode, indicate that reduction peak potential of furazolidone shifts in negative direction and reduction peak current
increases significantly at PANI/PPy modified polymer film electrode. PANI/PPy polymer electrode, characterized by FT-IR
spectroscopy, UV- vis spectroscopy, and SEM studies, was found stable and produced a pronounced response in long pH
range (5-12). Resistance of polymer film was determined by I-V characteristics. Proposed polymer electrode gave satisfactory
results in determination of furazolidone. |
