Preparation of a polypyrrole-lead dioxide composite electrode for electroanalytical applications.

A constant potential electrolytic method for the preparation of a new polypyrrole-lead dioxide composite electrode on glassy-carbon substrate is described. The method involves constant potential electrolysis (CPE) of 1M potassium nitrate containing 2mM lead acetate at + 1.100 V vs. SCE for about 10 min, followed by addition of 25mM pyrrole and subsequent… (More)
