Abstract

An electrochemical sensor based on Cu3(BTC)2 MOF-fabricated screen-printed carbon electrode (SPCE) was employed for Cd(II) detection. The Cu3(BTC)2 was synthesized via a straightforward solvothermal approach and characterized by XRD, FT-IR, TGA, and FE-SEM. The XRD of the synthesized Cu3(BTC)2 was in good agreement with the existing Cu3(BTC)2 (CCDC 112954). The FT-IR results revealed the absorption bands at 1368–1446 cm−1 and 1554–1640 cm−1 which may be ascribed to the bridged bidentate coordination of carboxylate groups in Cu3(BTC)2 MOF. The Cu3(BTC)2-modified electrode offers the facile electron transfer and greater electrochemical surface area compared to the bare electrode. The recovery of Cd(II) ranged from 102.68 to 115.36%, which proves the practical applicability of the Cu3(BTC)2/SPCE electrode.
