This contribution indicated how to anchor amine-decorated pores of Cu-MOF, Cu3 (BTC)2 (1), formulated Cu3(BTC)2@AMT (1@AMT) (where AMT=2-amino-5-mercapto-4,3,1-thiadiazole and BTC=1,3,5-benzenetricarboxlic acid or trimesic acid) as an efficient way to remove Cd (II) from an aqueous solution. Furthermore, the post-synthetic modification as exemplified in the context of functionalizing the MOF, 1 with AMT was performed, and the resultant structure was determined through X-ray Powder diffraction (XRPD), FTIR spectroscopy, and field emission scanning electron microscopy (FESEM). N2 adsorption-desorption by Brunauer-Emmett-teller (BET) has been determined to evaluate the specific surface area (7.49 m2.g-1) and the pore volume (0.04 cm3.g-1) of the sample. Herein, we study the effect of various crucial factors, including pH, contact time, and other background metal ions, on 1@AMT uptake capacity. Moreover, the reusability was studied and recycled without considerable loss of Cd (II) uptake capacity during five cycles. The resultant amine-functionalized MOF, 1@AMT, showed a high Cd (II) uptake capacity of 692.3 mg.g-1, surpassing that of the benchmark adsorbents. Our work thus paves the way for developing functionalized MOFs with significant affinity between the amide group and Cd (II) as a new type of platform with sufficient cadmium removal performance.
