Sorption Behavior of Zirconium Ions from Aqueous Solutions Using Different Inorganic Sorbents Based on Titanate

In this article, we explore the sorption behavior of Zr(IV) ions by lithium titanate (LiTi), magnesium titanate (MgTi), and lithium magnesium titanate (LiMgTi) sorbents. These sorbents, fabricated using the precipitation method, were used for the Zr(IV) sorption from aqueous solutions. We employed v...

Description
Summary:In this article, we explore the sorption behavior of Zr(IV) ions by lithium titanate (LiTi), magnesium titanate (MgTi), and lithium magnesium titanate (LiMgTi) sorbents. These sorbents, fabricated using the precipitation method, were used for the Zr(IV) sorption from aqueous solutions. We employed various analytical tools, including XRD, FT-IR, BET, SEM, and EDX, to examine the prepared sorbents’ structure, morphology, and functional groups. We also studied the effect of pH, time, initial metal concentrations, temperature, and interfering species on sorption. The kinetic data obey pseudo-first-order. Many isotherm models were utilised to investigate equilibrium data. The results of thermodynamic functions show an endothermic and spontaneous sorption process. Finally, the influence of the interfering species reveals that as the concentration of CaCl 2 , MgCl 2 , and NaCl increases, the Zr(IV) adsorption rate decreases. The investigation demonstrated that LiMgTi is suitable for retaining Zr(IV) from aqueous solutions and could purify effluent polluted with Zr(IV) ions.
