Thiol-functionalized UiO-66-NH₂ for Hg²⁺ adsorption and sensing

Abstract

Excessive levels of heavy metal ions in water has raised concerns to human health and environment. Metal-Organic Frameworks (MOFs) is a popular adsorbent material due to its high adsorption capacity and ability to adsorb various heavy metal ions. UiO-66-NH₂ can remove Hg²⁺ with adsorption capacity at 194 mg g^-1 and rate constant at 0.006 g mg^-1 min^-1. Furthermore, UiO-66-NH₂ was grown on polyvinylidene fluoride (PVDF) fiber for metal-sensing properties. UiO-66-NH₂ on PVDF fiber can be used as a sensor to detect and monitor concentration of various heavy metal ions existing in aqueous solution.
