PROCESS OF CONTAMINATION OF SOILS FROM RADIONUCLIDES Russian patent published in 1995 - IPC

Abstract RU 2050029 C1

FIELD: cleaning of environment. SUBSTANCE: process consists in treatment of soil contaminated with radionuclides with aqueous solution carrying inorganic ammonium salt and noncomplex inorganic iron salt. In this case pH of aqueous solution amounts to 2.0-3.0. Treatment is conducted with mass proportion of solution and soil from 12.5 to 41.5. Desorption degree ¹³⁷Cs after treatment amounts to 70-80% EFFECT: enhanced efficiency of process. 1 tbl
