Concentration and temperature dependence of viscosity of uranium solutions in H2O and 3 mol/L HNO3.
Viscosities of uranium solutions in H(2)O and 3 mol/L HNO(3) medium were measured by Ubbelhode flow viscometer in the concentration range of 0.5%-3.0% from 10 degrees C to 30 degrees C at 5 degrees C interval. Viscosity data were interpreted in terms of an empirical equation; eta =a(o)exp(b(o)M+c(o)M(2)). Values of coefficients a(o), b(o) and c(o) were calculated for all the three systems studied. Flow activation energies and thermodynamic parameters were also evaluated.
