Synthesis and Ion-Exchange Properties of Reproducible Stannic Molybdoarsenate. Separations of Ba²⁺–La³⁺, Mg²⁺–La³⁺, Sr²⁺–Y³⁺, and Sr²⁺–La³⁺

Synthesis, Characterization, and Sorption Behavior of a Novel Composite Cation Exchange Adsorbent

“…This sequence is in accordance with the hydrated radii of the exchanging ions . The ions with smaller hydrated radii easily enter the pores of the exchanger, resulting in higher sorption . The pH titration curves performed for LiOH–LiCl, NaOH–NaCl, and KOH–KCl systems show one inflection point (Supporting Information, Figure S1) which demonstrated monofunctional cation exchange behavior.…”

Synthesis and characterization of a new inorganic cation-exchanger—Zr(IV) tungstomolybdate: Analytical applications for metal content determination in real sample and synthetic mixture

“…One interesting property Zr(IV) tungstomolybdate that differentiated it from other exchange materials was that it can withstand temperature as high as 1000 • C with a loss of only 18% in ion-exchange capacity. Stannic tungstoselenate, stannic molybdoarsenate, zirconium iodomolybdate and stannic silicomolybdate [19][20][21][22] experience a drastic loss in ion-exchange capacity on heating in the temperature range of 100-1000 • C. A comparison of ion-exchange capacity data as a result of heating for different inorganic ionexchangers was depicted in Fig. 1.…”
