Description
Summary:A significant difference in behavior of Zr IV ions during their cocrystallization and sorption binding to hydroxyapatite (HAP) is demonstrated. When the concentration of doping ions exceeds 10 −4 mol L −1 , a chemical reaction with the formation of amorphous zirconium phosphate and complete dissolution of the sorbent occurs in the system rather than sorption. According to the X-ray diffraction and transmission electron microscopy (TEM) data, a similar reaction is also possible at lower concentrations of zirconium ions. The effect of doping ions on the morphology and structure of HAP is significantly lower for the cocrystallization introduction of Zr. In addition, according to high-resolution TEM data, doping ions can uniformly be distributed over the carrier surface or volume. Therefore, this method of binding method can be recommended for the preparation of a target HAP-Zr complex.
