Abstract: (57) This invention relates to a method of composite sorbents manufacturing on the basis of transition metal hexacyanoferrates and porous supporting materials. Sorbents, produced by this method have high efficiency recovery of cesium radionuclides (Up to 98,9%), strontium radionuclides (Up to 86,5%), thallium radionuclides (Up to 96,7%), low solubility in the water (less than 0,01%). Composite sorbents, produced by this method, have high efficiency in potable water cleaning to remove radionuclides, to add them into the daily diet of animals, because they decrease the quantity of cesium radionuclides in muscular tissue (in 10-12 times), in milk (in 10-20 times), and can be used for cleaning of AES secondary water.
