摘要: Abstract The H + /K ion-exchange process in γ-Ti(HPO 4 ) 2 ·2H O was studied, titration and hydrolysis curves exchange isotherms being obtained at 278.15, 298.15, 313.15 328.15 (±0.1) K. Three differentiated processes of substitution crystalline phases 25, 50 100% conversion were reached. equilibrium constants, the standard molar Gibbs free energies, enthalpies entropies reaction determined.
