In this study, a novel on-line pre-column electrochemical instrument (PECI) coupled with high-performance liquid chromatography (HPLC) was developed, and a novel method based on PEC–HPLC-UV for amplifying the ultraviolet (UV) response of iodate (   (IO   3−   )   ) was studied. Iodate undergoes reduction in the PECI, and the resulting I −  was injected to an HPLC system and detected by a UV detector. For    (IO   3−   )    analysis, conditions that can influence the reduction efficiency, including applied potential, pH value and salt concentration, were investigated in detail. In an appropriate condition, the UV response of iodate after passing through PECI was almost 10 times more than that of the initial form with good precision (relative standard deviation 2.0–4.3%). The detection limit and quantity limit were 9 and 20 ng, respectively. It can be concluded that the proposed method is simple and highly sensitive.
