Abstract

Dispersion number is a direct indication of the settling and coalescing property of solvent with the given aqueous system. By dispersion number measurement, suitability of solvent can be characterized for post-mixing settling operations during solvent extraction. Tri-isoamyl phosphate (TiAP) is being proposed as extractant, alternate to conventional extractant TBP for nuclear solvent extraction processes. In this work, TiAP is characterized by measuring the dispersion numbers for 36% TiAP in n-dodecane and 100% TiAP solutions, equilibrated with aqueous nitric acid solutions of varying concentrations.
