摘要：
The H+/Sr2+ ion-exchange in gamma-Ti(HPO4)2.2H2O was studied. Exchange isotherms and pH curves were obtained at 298.15, 313.15 and 328.15(+/- 0.1) K. The half-exchanged phase TiHSr0.5(PO4)2.3H2O (interlayer distance 1.34 nm) was detected. The equilibrium constants and the standard molar Gibbs free energy, enthalpy and entropy of the exchange reaction were determined.
