Abstract

Detection of radioactive iodide ions (I^-) is important for protecting human beings from the hazards of radioactive pollution. Herein, we present a protocol for detecting I^- using a zirconium(IV)-enhanced strategy. We describe steps for optimizing the I^- detection approach, establishing standard curves, and finally applying the approach. The use of zirconium(IV) greatly improves the detection performance and endows this approach with an ultralow detection limit of 0.176 nM together with wide applicability in various aqueous environments. For complete details on the use and execution of this protocol, please refer to Feng et al. (2022).¹.
