摘要	Viscosity and density for aqueous VOSO4 solution have been measured in the concentration range of (0.05 to 03) mol.kg(-1) at different temperatures from (283.15 to 323.15) K. On the basis of the measurements, the activation energy of viscous flow has been calculated by Arrhenius equation. A predicting function for the viscosity of aqueous VOSO4 has been proposed based on the viscosity coefficients A and B determined from Jones-Dole equation. In addition, the VO2+-water interaction and its effect on the structure of solvent according to the B-coefficient of VO2+ in dependence of temperature have been discussed. Using the B-coefficients, furthermore, the activation parameters for viscous flow of the solution, Delta mu(not equal 0)(1), Delta mu(not equal 0)(2), and other thermodynamics parameters Delta S-2(not equal 0), Delta H-2(not equal 0), and Delta C-p2(not equal 0) were evaluated. Finally, another empirical model of the viscosity has been investigated on, the basis of the Eyring equation with the AAPD of 1.81%, and the maximum relative deviation is 2.77% below 313.15 K, but up to 7.01% above 323.15 K. Both predicting equations for the viscosities of aqueous VOSO4 are both in good agreement with the experimental results. (C) 2016 Elsevier B.V. All rights reserved.
