Synthesis, Ion-Exchange Properties, and Analytical Applications of Anilinium Tin(IV) Phosphate

Abstract

A new inorganic ion-exchanger anilinium tin(IV) phosphate (ATP) has been synthesized under varying conditions. The effects of mixing ratio of reagents and the pH of the mixture on the properties of the material have been studied. The sample ATP1 has been chosen for detailed studies, such as ion-exchange capacity, chemical and thermal stabilities, chemical composition, pH titration, break-through curve, and IR analysis. Distribution coefficients of 16 metal ions have been studied in water, hydrochloric acid and acetone–hydrochloric acid media. On the basis of Kd values some analytically important separations of metal ions have been achieved on the small columns of anilinium tin(IV) phosphate.
