Abstract
The invention belongs to the technical field of iodine adsorption materials, and provides an iodine adsorption material and a preparation method thereof, Co (NO3) 2.6 H2O, Vlm and AIBN are mixed with a proper amount of DMF according to a molar ratio of (16-24): (100-140): (1-5), and a first product is obtained after reaction; and washing and drying the first product to obtain the Co-Vlm6. Co-Vlm6 and polyether sulfone (PES) are mixed according to the mass ratio of 4: (5-9), a proper amount of NMP is added for mixing, and a granulation solution is obtained through sealing and uniform stirring; and injecting the granulation liquid into a tank of a granulator, dripping the granulation liquid into water to form a sphere, and washing after forming to obtain the Co-Vlm6 / PES composite adsorbent. The Co-Vlm6 / PES composite adsorbent disclosed by the invention has the properties of large adsorption capacity, high rate and good selectivity on I3 <->, and is easily and quickly separated from an adsorption solution.
