MgO-supported CuO with encapsulated structure for enhanced peroxymonosulfate activation to remove thiamphenicol

Separation and Purification Technology, 2022
Copper-base catalysts with high load content of CuO were commonly utilized to activate peroxymonosulfate (PMS) for removal of contaminants but limited catalytic efficiency and increased risk of copper ion leaching restricted their use.

Fate and exposure risk of florfenicol, thiamphenicol, and antibiotic resistance genes during composting of swine manure.

Science of the Total Environment, 2022
Livestock manure is an important source of antibiotic resistance genes (ARGs) spreading to the environment, posing a potential threat to human health. Here, we investigated the dissipation of florfenicol (FF) and thiamphenicol (TAP), and their effects on

Efficient removal of antibiotic thiamphenicol by pulsed discharge plasma coupled with complex catalysis using graphene-WO3-Fe3O4 nanocomposites.

Journal of Hazardous Materials, 2020
Pulsed discharge plasma (PDP) induced complex catalysis for synergetic removal of thiamphenicol (TAP) was investigated using graphene-WO3-Fe3O4 nanocomposites. The prepared samples were characterized systematically in view of the structure and morphology,

Integrating peroxidase-mimicking MOF-based composite nanozymes with molecular imprinting for dual-mode thiamphenicol sensing in animal-derived foods.

Food Chemistry
Since thiamphenicol (TAP) poses a great threat to food safety, there is an urgent need for accurate determination. In this study, we successfully synthesized N,S-CQDs/MIL-101(Fe) composite nanozymes with a high peroxidase-like activity that catalyzed the

In vitro activity of thiamphenicol against drug-susceptible and drug-resistant strains of Mycoplasma genitalium.

Journal of Antimicrobial Chemotherapy
OBJECTIVES Mycoplasma genitalium causes a range of urogenital infections. It is inherently resistant to beta-lactam antibiotics, and the first and second-line treatments recommended are azithromycin and moxifloxacin, respectively.
