A comparative study on textural characterization: cation-exchange and sorption properties of crystalline α-zirconium(IV), tin(IV), and titanium(IV) phosphates
TL;DR: The ion exchange capacity of alpha-titanium phosphate is greater than those of other phosphates, which is explained on the basis of the surface behavior, disorderness of the system, degree of hydrolysis of incoming guest adsorbate metal ions, and structural steric hindrance of the exchangers during adsorption and sorption.

Crystalline insoluble salts of polybasic metals—I Ion-exchange properties of crystalline titanium phosphate
TL;DR: On refluxing amorphous titanium phosphate with phosphoric acid, a crystalline product was obtained, which exhibits high ion exchange capacity for Li+ and Na+ (∼7 m-equiv/g), while K+ and Cs+ uptakes are negligible in acid solution as discussed by the authors.
