In this work, a new composite film electrode based on Dawson-type polyoxometalate α2K7P2VW17O62·18H2O (P2W17V) and accessory copper oxide nanoparticles (CuO NPs) with a composite of carbon nanotubes (CNTs) was successfully proposed and employed for iodate (IO3 ) analysis. Highly stable determination of IO3 was achieved by a combination of cyclic voltammetric and chronoamperometric methods performed on this layer-by-layer (LbL) self-assembly composite film electrode. For the tricomponent composite film, the amperometric response time of iodate (defined as the time to achieve 95% steady-state current) was estimated to be 2 s, confirming the faster electron transfer rate in the tricomponent composite film. This iodate sensor with 10 bilayers has a linear range of 1.25 × 10 -7 to 1.63 × 10 -4 M, a low detection limit of 1.5 × 10 -8 M (S/N = 3), a high sensitivity of 4.82 mA mM -1 IO3 and an excellent anti-interference performance. In addition, the composite film could also be applied to detect iodate in table salt. The as-prepared sensor can be used for detecting iodate with a good average recovery of 100.1%, indicating the well reliability of the present sensor for iodate determination in table salts. This approach may open a new path for the rational design of high-performance tricomponent composite film electrochemical sensors.
