The Institute of General and Inorganic Chemistry offers consumers sorbents selective for 85Sr and 60Co radionuclides on the basis of a manufacturing agreement and is looking for partners to conclude a distribution services agreement.
The creation of new materials and technologies is due to the need for the safe handling of liquid radioactive waste. At present, sorption materials with high selectivity for both 85Sr and 60Co radionuclides are practically not described.

The theoretical significance of the development is to establish the mechanism of action of hydroxyethylidene diphosphonic acid on the crystalline and porous structure of sorbents based on hydroxyapatite.
Advantages and Innovations
Adsorbents with a developed mesoporous structure (pore size 15..20 nm, sorption volume 0.60..0.80 cm3/g), specific surface area 200..250 m2/g, containing phosphonic groups, the presence of which imparts high selectivity to sorbents in relation to radionuclides 85Sr and 60Co. Sorbents are characterized by 8-10 times higher selectivity in relation to radionuclides 85Sr and 60Co in highly saline solutions (up to 50 g l) as compared to analogs (distribution coefficients are 103-104 cm3/g).

The method of obtaining sorbents with a given nature of the surface (the presence of phosphonic groups) and a porous structure (size and volume of pores, specific surface) ensures the production of sorbents with a high affinity for 85Sr and 60Co radionuclides and a high rate of sorption from aqueous solutions.
