Аннотация:By measuring the hydrodynamic characteristics (viscosity, density of extraction mixture, and interfacial tension) and determining the composition of degradation products by the IR, CMS, and nuclear magnetic resonance methods, the efficiency of using solutions of methylamine and guanidine carbonates at the stage of intracycle regeneration was evaluated. It has been experimentally proven that, when using these solutions, the same efficiency is achieved as when using a sodium bicarbonate solution. The main products of radiation destruction of the 30% Tri-n-butyl-phosphate in Isopar-M extraction mixture irradiated after saturation with nitric acid are determined: dibutyl phosphoric and monobutyl phosphoric acids, carboxylic acids, ketones, carbonyl compounds, and hydrocarbons.
