Abstract

Efficient decontamination of radioactive Ba²⁺ is of great significance to human health and environmental safety. Herein, an adsorbent based on the sulfonic acid functionalized Zr-MOF has been successfully developed, which could efficiently decontaminate radioactive Ba²⁺ with excellent selectivity, recyclability, a high adsorption capacity up to 60.8 mg g⁻¹ as well as a short adsorption kinetic time of less than 5 min. This outstanding adsorption performance is attributed to the strong affinity between Ba²⁺ and high density –SO₃H active sites in MOFs which were introduced by an in situ ligand modification strategy during the assembly of MOFs.
