Abstract
Composite film of polyaniline (PANI) and tungsten oxide (WO3) was electrodeposited by cyclic voltammetric technique from a solution of aniline and tungstic acid. The obtained WO3/PANI film displayed a significant enhancement of electrocatalytic activity for iodate reduction and a better stability than that of pure WO3 and PANI films. Result of amperometric experiment revealed a good linear relationship with concentration of IO3− from 20 to 500 μM, with a high sensitivity of 0.54 μA/μM and a detection limit of 2.7 μM for the determination of iodate. This composite film was also successfully applied in determination of iodate in commercial table salt.
