Formation of solid phases of titanium(IV) in phosphate solutions was studie
d in a wide range: of concentrations of hydrogen and acidoligand ions toget
her with the variation of the composition of phosphates depending on soluti
on composition. Reasons for the observed phenomena and the effect of whethe
r the acidoligand is mono-, bi-, or tridentate on ion-exchange properties o
f titanium(TV) phosphates were studied.
