โœฆ Synopsis

A modified carbon electrode for the amperometric determination of hydrogen peroxide is described. By deposition of a 15-nm thick layer of a 40:60 mixture of palladium and gold on the surface of the electrode the overvoltages for both the oxidation and 'the reduction can be decreased by at least 800 mV. When applied as an electrochemical sensor in a flow-injection system, linear calibration graphs were obtained between lo-' and 5 x 10e3 M hydrogen peroxide. The modified electrodes were stable for months.

## Abstract A hydrogen peroxide sensing electrode was prepared by incorporating cobalt(II) octaethoxyphthalocyanine [CoPc(OEt)~8~] into a carbon paste (CP) matrix. The CoPc(OEt)~8~โ€modified electrode could oxidize hydrogen peroxide at lower potentials than a CP electrode with unsubstituted cobalt p
