摘要	The effective extraction and regeneration of radioactive iodide remains an urgent concern for safe nuclear energy utilization. Herein, we developed a novel electrochemically triggered iodide-vacancy BiOI film, which exhibited excellent I- ion extraction capacity of 328.3 mg.g(-1). Especially, due to the ion vacancy trap effect, the film showed high selectivity towards I- ions in the existence of a large number of competitive anions. Additionally, the electrochemically switched ion extraction (ESIE) process with this iodide-vacancy BiOI film possessed fast extraction kinetics and high stability. More importantly, the trapped I(- )ions were easily desorbed from the film without the secondary pollution during the ESIE process and meanwhile, the iodide-vacancy BiOI film was able to be completely regenerated. It is expected that such an iodide-vacancy BiO film with ESIE could become a promising process for the selective extraction of I- ions from the radioactive water.
