A novel method for the determination of phenol at a carbon-paste electrode coated with over-oxidized polypyrrole and polyvinylpyrrolidone films (OPPy/PVP) has been developed. Phenol in a 0.1 M KC1 solution was preconcentrated during an open circuit for 10 min, and was then determinated in a phosphate buffer (pH 10.0). A sensitive oxidation peak was observed at about + 0.48 V (vs. Ag/AgC1). The peak current was well-proportional to the phenol concentration in a very wide range from 1.0 × 10^<-6> to 1.0 × 10^<-3> M, and the detection limit was 1.0 × 10^<-7> M. The modified electrode with high sensitivity and selectivity is easy to prepare, and can be applied to the determination of phenol in waste water.
