Effect of the nature of the components of extraction systems used to extract radionuclides on interfacial tension. V. Radiation polymerization products of tri-n-butyl phosphate

This paper examines the effect of the polymerization products of tri-n-butylphosphate (TBP) on stratification of normal and inverse emulsions and the interfacial tension in systems of 30% TBP in n-dodecane with water, 5% aqueous solution Na2CO3, and a solution of 3 moles/liter HNO3. It is shown that in these systems there is a direct correlation between the interfacial tension and the phase stratification rate. Small additions of a neutral fraction of the polymerization products do not exert any appreciable effect on the interfacial tension and the phase stratification rate in the investigated systems
