Key Points

The research aims to develop a dual-functionalized MOF for efficient Au(III) adsorption from water.
Developed UiO-66-AVIM-TSC via in-situ polymerization of an amino-functionalized imidazolium ionic liquid.
Utilized electrostatic and coordination interactions to enhance Au(III) binding efficiency.
Conducted experiments in aqueous solutions to evaluate adsorption performance.
UiO-66-AVIM-TSC exhibited significantly higher Au(III) adsorption capacity compared to unfunctionalized UiO-66-NH2.
Achieved a selectivity factor for Au(III) over other ions in solution, indicating a strong affinity for gold ions.

Implication

Demonstrates efficient Au(III) adsorption using dual-functionalized MOF, suggesting a novel approach.

Abstract
