Radioiodine is highly radioactive and acutely toxic, which can be a serious health threat, requires effective control. To fully utilize an adsorbent reduce the overall production cost, successive recycling applications become necessary. Here, 3D formicary-like δ-Bi2O3 (FL-δ-Bi2O3) aerogel adsorbents were synthesized using one-pot hydrothermal method. In this hybrid structure, abundant flowerlike (MR-δ-Bi2O3) microspheres inlaid into interconnected ant nest channel, forming hierarchical applied as efficient with easy recovery for radioiodine removal. Notably, FL-δ-Bi2O3 exhibited very high uptake capacity of 2.04 mmol/g by insoluble Bi4I2O5 phase. Moreover, worked in wide pH range 4-10 displayed fast kinetics excellent selectivity due to porous network larger specific surface area. Importantly, process easy, only tweezers directly move from one reaction system another. Therefore, may promising practical selective capture iodide.
