%X Based on the solution theory,the thermodynamical approaches to calculation of the component activity coefficients in organic phases,to determination of the thermodynamical equilibrium constant of metal extraction reaction and to predic- tion of the metal extraction equilibrium distribution are presented.Three neutral solvent-metal extraction systems,TBP-UO_2Cl_2,TBP-UO_2(NO_3)_2 and (C_7H_(15))_2SO-UO_2 (NO_3)_2,have been tested solely by thermodynamical method.Seven models have also been examined and compared,Among them,the Scatchard-Hildebrand and Guggenheim ones are more simple and convenient for calculating practice.These two models have tried all available to both quarternary and ternary organic phases.
