摘要:

The H+/Na+ion-exchange process in Y Ti(HP04)22H20 was studied. Exchange isotherms, titration and hydrolysis curves were obtained at 25.0, 40.0 and 55.0 (+0.1)°C. Three different substitution processes and three hydrated crystalline phases of 25, 50 and 100% of conversion were detected. Equilibrium constants, free energies and entropies of the exchange reactions were determined.
