“…35,36 Peaks at 3503 cm −1 and 3386 cm −1 associated with -NH 2 in the ligand, and they are covered by the -OH peak of H 2 O in the MOF. 37,38 New peaks at 551 cm −1 and 751 cm −1 in both as-made and activated Ce-UiO-66-NH 2 confirm the generation of Ce-O bonds. 39 XPS characterization was also conducted to further demonstrate the successful synthesis of the MOF material.…”

“…It can be preliminarily inferred that 23% of Cr (VI) adsorption originated from the adsorption site. Zhang [23] used UiO-66-NH 2 to remove 100 mg•L −1 Cr (VI) solution, and obtained q m of 252 mg•g −1 using the Langmuir model. Based on this, the ligand of UiO-66 was replaced with 2-amino terephthalic acid containing an amino functional group.…”

Developing high-performance adsorbents for heavy metal (Cr (VI)) removal is essential for sustainable environments, but it is still challenging. Herein, a simple solvothermal method was proposed to fabricate Zr-MOFs (UiO-66), which was innovatively modified by amino groups to enhance the adsorption capacity of Cr (VI). The effects of the content of amino-functionalized ligands on the adsorption capacity and the influence of adsorbent content, solution pH, adsorption time, and adsorption temperature on the adsorption process were systematically investigated. Importantly, the pore structure and defect structure of UiO-66 can be finely regulated by adjusting the amino modification process. The adsorption process was fitted and analyzed using the kinetic model and the isotherm model. Impressively, the adsorption capacity of the amino-modified UiO-66 (UiO-66-NH2) was greatly improved. These findings indicate that the surface functional group modification of MOFs is a promising method for adjusting their structure and improving their adsorption capacity.
