Advancing Arsenic Water Treatment Using UiO-66 and Its Functionalized Metal-Organic Framework Analogs.

ABSTRACT: Arsenic contamination in water remains a critical global health challenge, affecting millions and causing severe diseases including cancer, skin lesions, and cardiovascular disorders. Adsorption using metal-organic frameworks (MOFs), particularly zirconium-based UiO-66 and its derivatives, offers a promising and sustainable approach for arsenic remediation due to their high surface area, tunable porosity, and strong chemical stability. Functionalized UiO-66 variants (e.g., -NH₂, -SO₃H, -COOH, -SH), metal-doped, or composite forms such as Fe₃O₄@UiO-66 exhibit arsenic adsorption capacities between 20 and 150 mg g^-1, depending on synthesis and surface chemistry. Optimal adsorption occurs within pH 4-8, while high salinity or competing ani
