- Abstract
Extraction power of solvent depends upon the physical properties of the system. Tri- n-butyl phosphate (TBP) in dodecane is a versatile solvent used in the nuclear fuel reprocessing like PUREX process. The study of physical properties like density, viscosity, interfacial tension and solubility for TBP-nitric acid-dodecane system will be helpful in carrying out different extraction studies during PUREX process. Thus, physical properties like density, viscosity, interfacial tension and solubility have been measured for TBP-nitric acid-dodecane system using pycnometer, viscometer, pendant drop method and high performance liquid chromatography respectively. It has been observed that density and viscosity increases but interfacial tension and solubility decreases with the concentration of TBP in dodecane-nitric acid system. Physical properties of 30 % TBP-nitric acid-dodecane system have also been studied in detail. All these studies will also be useful in stripping out dissolved TBP from the nuclear waste.
