Electrocatalytic oxidation of ascorbic acid (AA) in aqueous buffer solutions at thep-tetracyanoquinodimethane (TCNQ)-, ferrocene (Fc)-, 1 ,I '-dimethylferrocene (DMFc)-, and tetrathiafumene (TI'F)-modified graphite electrodes is carried out at each modifier's redox potentials. Over the linear range
Polypyrrole, an electronic conducting polymer, is used as a matrix for the dispersion of Pt particles . These particles can be included by two methods, viz . (1) by electrochemical deposition of platinum particles on a polypyrrole covered glassy carbon disc and (2) by incorporation of Pt particles d
