Selective Separation of Zr(IV) from Simulated High-Level Liquid Waste by Mesoporous Silica.

ABSTRACT: The efficient separation of Zr(IV) ions from strong acidic and radioactive solutions is a significant challenge, especially in the context of the aqueous reprocessing of nuclear fuels. The complexity of such solutions, which are often characterized by high acidity and the presence of radioactive elements, poses formidable challenges for separation processes. Herein, several mesoporous silicas (HMS, MCM-41, KIT-6, and SiO₂-70 Å) with excellent acid and radiation resistance properties were employed as sorbents to remove Zr(IV) ions from simulated high-level liquid waste. The batch experiments were designed to investigate the influence of adsorption time, HNO₃ concentration, initial Zr(IV) concentration, adsorbent dosage, and temperature on the adsorption behavior of Zr(
