摘要	This paper reports the densities of aqueous VOSO4 that were measured by an Anton Paar DMA 4500 M from 0.0500 mol.kg(-1) to 3.000 mol.kg(-1) at 283.15 to 323.15 K The apparent molar volume, V-phi(B), the partial molar volume of VOSO4, (V) over bar (B), the apparent molar expansibility of the solute, phi(E), and coefficient of thermal expansion of the solution, alpha, were calculated. First, these properties described above have been discussed with the temperature and concentration variation. Then the values of the apparent molar volume, V-phi(B), were fitted to Pitzer's model for volumetric properties by the method of the least squares, which allowed the partial molar volume of the VOSO4 at infinite dilution, (V) over bar (0)(B), and Pitzer's parameters, beta((0)V)(MX), B-MX((1)V) and C-MX(V), to be obtained. The small standard deviations of the fitting show that Pitzer's model is also appropriate for representing the volumetric properties of aqueous solutions of VOSO4. Using the data from literature, the partial molar volume of the ion VO2+ at infinite (V) over bar (0)(C), was discussed and the result showed that the negative value of (V) over bar (0)(C) can be attributed to strong hydration of VO2+ as other divalent ions.
