ABSTRACT
A voltammetric electrode based on a poly(3-methylthiophene) (PMT) film for the differential pulse stripping voltammetric (DPSV) determination of iodide was developed. Gold electrodes were first coated with PMT, and iodide was then doped into the polymer film by electrochemical oxidation of iodide at 0.75 V. The effects of various electrochemical parameters, such as electroyte type and its pH, deposition potential, deposition time, and precipitation time, were examined. Using DPSV, the PMT electrode was found to be suitable for the measurement of iodide concentrations above 1 × 10−9 M.
