| titleOfInvention | A bismuth-loaded inorganic porous iodine adsorption material and its macro-scale preparation method |
| abstract | The invention relates to the technical field of spent fuel reprocessing, in particular to a bismuth-supported inorganic porous iodine adsorption material and a macro-preparation method thereof, comprising the following steps: calcining and activating the inorganic porous carrier and measuring the saturated water absorption of the activated carrier; 1-3 times the saturated water absorption of the carrier, adding the bismuth-containing impregnating solution into the carrier, milling and ultrasonicating, drying and then reducing to obtain the iodine adsorption material. The invention effectively overcomes the technical problems such as difficulty in effective loading of bismuth element, difficulty in scale-up preparation and production of more waste liquid by the conventional excess impregnation method by organically combining and improving methods such as equal-volume impregnation, grinding and ultrasonic vibration. The adsorption capacity of the finally obtained iodine adsorption material is about 400 mg/g, which is twice that of commercially used silver-based adsorbents, and has broad application prospects. |
