METHOD FOR PRODUCING CHEMICAL SORBENT TO ABSORB NUCLEAR FUEL FISSION PRODUCTS Russian patent published in 2006 - IPC G21F9/02 B01D53/02 B01D53/34 B01J20/22 

FIELD: environment protection from radionuclides.

SUBSTANCE: proposed method for producing chemical sorbent to absorb nuclear fuel fission products (radionuclides of iodine, ruthenium, and their volatiles) includes impregnation of activated carbon in triethylene diamine followed by its drying at temperature of 110-130 °C. For the purpose use is made of activated carbon produced from raw bituminous coal having micropore volume v_mp = 0.28-0.33 cm³/g and total pore volume v_Σ = 0.85-1.0 cm³/g. Activated carbon is impregnated until triethylene diamine content is reduced to 1-2% of base mass. Then chemical sorbent obtained in the process is dried out and sifted.

EFFECT: enhanced quality of chemical sorbent obtained.
