Robust degradation of tetracycline antibiotic through recyclable Fe₃S₄/Ti₃C₂MXene composites

Abstract

The efficient and sustainable removal of Tetracycline (TC) from wastewater is a matter of great significance. In this study, we present a novel technique that effectively degrades TC by harnessing...

Fenton-like Catalysts Based on Graphitic Carbon Nitride Nanosheets Decorated with Fe3O4 Nanoparticles for Removal of Colorless Tetracycline

“…In the case of the Fe 2p spectra (Figure D), two broad peaks were obtained at 710.7 and 724.5 eV; these can be attributed to the spin–orbit peaks of Fe 2p 3/2 and Fe 2p 1/2 , respectively, which could be fitted by five peaks in total. The peaks at 710.5 and 723.4 eV denote Fe in the second oxidation state, and the peaks at 712.2, 724.5, and 726.1 eV correspond to the Fe 3+ state, suggesting the existence of Fe 3 O 4 on the CN surface. − …”

Heterogeneous Activation of Sulfite by a Three-Dimensional Printed Hierarchically Porous Copper Catalyst for the Degradation of Tetracycline Hydrochloride in Water

“…For pathway I, the generated P1 was transformed into P2 ( m / z = 274) by the elimination of −CH 3 and −OH followed by the generation of P4 ( m / z = 219) through demethylation and decarboxylation reactions . In terms of pathway II, P1 was transformed into P5 ( m / z = 173) via the leaving group of −CH 3 and −OH . Regarding pathway III, P1 was decomposed into P3 ( m / z = 251) through the dehydroxylation and demethylation reactions .…”

“…40 In terms of pathway II, P1 was transformed into P5 (m/z = 173) via the leaving group of −CH 3 and −OH. 41 Regarding pathway III, P1 was decomposed into P3 (m/z = 251) through the dehydroxylation and demethylation reactions. 42 Eventually, the produced P3, P4, and P5 intermediates were mineralized into some small molecule products including P6 (m/z = 142), P7 (m/z = 136), P8 (m/z = 126), P9 (m/z = 108), and P10 (m/z = 57) through the ring-opening reactions, which were finally further decomposed into H 2 O, CO 2 , and inorganic ions (i.e., NH 4 + ).…”

Deep eutectic solvent-assisted synthesis of La–Ce hybrid nanorods for the colorimetric determination of tetracycline in foods

“…Antibiotics are indispensable in human life, specifically in the treatment of diseases and their prevention. 1,2 Tetracycline antibiotics (TCs), a type of broad-spectrum antibiotic, include oxytetracycline (OTC), demeclocycline (DMC), and tetracycline (TC), which are used in human therapy and as agricultural feed additives. 3,4 TCs are at the top of the list of antibiotics produced and used globally because they have few side effects and good bacteriostatic properties, and are inexpensive.…”
