Sponge-inspired reassembly of 3D hydrolyzed collagen aerogel with polyphenol-functionalization for ultra-capturing iodine from airborne effluents

The efficient capture of radioactive iodine (I-129, I-131) and radon (Rn-222) is crucial to the development of nuclear energy in spent fuel treatment. Herein, we successfully synthesized a new type of three-dimensional hydrolyzed collagen aerogel immobilized with catechin ([email protected] aerogel) as an effective adsorbent to remove iodine and radon through enzymatic hydrolysis, dialysis, freeze-drying, immobilization, and cross-linking. The...
