  Efficient removal of iodide (I−) and iodate (IO3−) from aqueous solution is highly desirable for waste disposal and remediation of radioiodine contamination. We report here a bifunctional anion exchange resin Purolite A530E for the effective I−/IO3− adsorption, which shows a priority anion-exchange affinity for I− (99%) over IO3− (9.7%). The maximum adsorption capacity for I− is 275.16 mg·g−1 fitted by the Langmuir isotherm model, much higher than most adsorbents. Furthermore, Purolite A530E exhibits great selectivity for I− over competing anions, which endows the resin with promising I− remediation that over 99% I− can be removed from simulated Hanford groundwater (HGW).
