The application of eda interactions for explaining and forecasting the extractive ability of elementoorganic reagents

Consideration is given to applicability of the principle of free energy linearity for explamation and forecasting of extraction ability of organic phosphorous compounds (OPC) in the processes, proceeding according to the mechanism of electron donor-acceptor interactions. Linear equations with high correlation coefficients were obtained for the process of extraction of nitric acid, actinide (An=V, Np, Pu, Am) and zirconium nitrates by neutral OPC. These semiempirical equations, relating donor properties and OPC electronic structure with their extraction ability, enable to forecast rather reliably the behaviour of heterophase solvent extraction systems
