Tetracycline removal from aqueous solution using zirconium-based metal-organic frameworks (Zr-MOFs) with different pore size and topology: Adsorption isotherm, kinetic and mechanism studies

Jing Xia et al.

Summary: Three zirconium-based metal-organic frameworks, UiO-66, NU-1000, and MOF-525, demonstrated excellent adsorption performance for tetracycline removal. The adsorption kinetics were best described by the pseudo-second-order model, with equilibrium rapidly reached within 40 minutes on UiO-66 and NU-1000, and within 120 minutes on MOF-525. The Sips model provided the best fit for the adsorption isotherms, with high maximum Sips adsorption capacities reported for all three MOFs. The pi-pi interaction was found to play a crucial role in the adsorption process.
