Abstract

This present study investigates the utilisation of Ag electrodes fabricated from recycled recordable compact discs (CD-R) for the amperometric determination of hydrogen peroxide. The analytical curve was linear up to at least 30 mM hydrogen peroxide with a sensitivity of 21.89 ?A/mM over this range. A corresponding detection limit of 17.7 ?M, based on a signal-to-noise ratio of three was recorded. The developed electrode represents a simple, inexpensive, reliable method for the determination of hydrogen peroxide, avoiding extended and complex multi-step fabrication as it is readily fabricated from recycled materials. It has a number of potential applications, including environmental, industrial, physiological and home security, especially where single use and disposability could be beneficial.
