Karazin popup.description2 The purpose of the work -study of the conditions of the forming the two-phase systems on base water solution of the polyethylene glycols of the different molecular weights and inorganic salts (the carbonate, sulphate, phosphate, thiocyanate) depending on concentrations of the salts, molecular weight of the polymer and pH solution, determination dug of the cations and anions in process of the forming the two-phase systems, motivation of the choice of the two-phase systems on base of polyethylene glycols different molecular weights for extraction separations and division radioactive nuclides of the product fissions.In the work explored phase balances in system PEG - inorganic salt - water at temperature 293,15 K.The studied conditions of the forming the two-phase systems on base water solution of the polyethylene glycols of the different molecular weights and inorganic salts (the carbonate, phosphate, sulphate, thiocyanate) depending on pH solution and concentrations of the salts. It is determinate composition of equilibrium phases. It is installed that main contribution to processes of the forming the two-phase systems contributes anion of salts, influence of cations small. It is shown that on salting-out polyethylene glycol from solution affects the row a factor: position anion of salts abreast Gofmeystera, concentration to inorganic salt-salting-out, molecular weight polyethylene glycol and its concentration, acidity of the solution polyethylene glycols, salts of alkaline metals, two-phase systems, phase diagrams, phase balances, biphasic curves, area of heterogeneous, salting-out.
