Abstract
Published data were systematized and new data were obtained on extraction of nitric acid, nitrates of uranium, neptunium, and plutonium in various valence states, thorium nitrate, and zirconium nitrate, and also on the effect exerted on their distribution ratios by temperature and other components present in the system, with 30% TBP in paraffin diluent used as organic phase. Data on the extraction of pertechnetic, acetic, formic, hydrazoic, hydrochloric, and dichromic acids and/or on the coextraction of their anions with U(VI) and Zr were obtained. Refined equations based on A.M. Rozen’s model were suggested for mathematical description of the extraction of the above components. These equations include the concentration extraction constants as polynomial functions of the solution ionic strength and take into account changes in the phase volumes upon mass transfer. Principles of stepwise calculation of extraction cascades in the steady-state mode, with data output in the tabular form and possibility of their transfer into MS Excel, are briefly described. The user’s interface is shown, and examples of head extractor calculation are presented.
