A single pump cycling-column-switching technique coupled with homemade high exchange capacity columns for the determination of iodate in iodized edible salt by ion chromatography with UV detection

► Proposal and application of a single pump cycling-column-switching technique in IC. ► Homemade columns were adopted for the separation of iodate and chloride. ► Determination of iodate in iodized edible salt without any pretreatment.
