Presence of dissolved tri-n-butyl phosphate (TBP) in the aqueous nitric acid solutions, can lead to runaway reactions in presence of nitric acid at temperature more than 130o C. Therefore, the concentration of dissolved TBP in the aqueous nitric solutions is an important control parameter for safe operation of product/waste evaporators. The experimental measurements of refractive index of six aqueous solutions of TBP in the range of 0-400 mg/L were performed and results were correlated in form of Redlich-Kister models. As an alternate to conventional chemical analysis and other instrumental techniques, a correlation, based on the experimental data, can be used to estimate the TBP content of aqueous nitric acid solutions.
