Abstract
Preparation of poly(2,2-bithiophene) modified platinum electrode to detect catechol in the presence of a common interferent have illustrated improved electrochemical reversibility, selectivity and sensitivity compared to conventional electrodes. Cyclic voltammograms and Scanning Electron Microscopy data will be discussed to explain the optimization of preparation of the poly(2,2- bithiophene) -modified platinum electrode for the detection of catechol in the presence of a common interferent such as ascorbic acid.
