The solubility of zirconium(IV) hydrous oxide was measured in the hydrogen ion concentration (pHc) range from 1 to 13 at 25 °C. The experiment was carried out with I=0.1, 0.5 and 1.0 mol/dm3 (M) of NaClO4 solution. The concentration of Zr was measured by ICP-MS after separating the aqueous phase from the solid phase by ultrafiltration methods. Some differences between the obtained values and literature data were observed due to the size distribution of chemical species. In the lower pHc region, the size distribution of filtrate species was investigated by different pore-size filtration in the range of 3 k to 100 kDa NMWL (nominal molecular weight limit) membranes. The solubility values of mononuclear species were obtained by the Flory model, and by using the specific ion interaction theory (SIT) for ionic strength corrections and the known literature value of the hydrolysis constant β1°, the tentative value of the solubility product (Ksp°) was determined to be −56.94±0.32.
