1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7) belongs to piperazine derivatives. A form in which piperazine is commonly available industrially is as the hexahydrate, C4H10N2. 6H2O, which melts at 44 °C and boils at 125–130 °C. Piperazines are very broad chemical group, covering a wide range of drugs from antidepressants to antihistamines. The connecting property of all these chemicals is the presence of a piperazine functional group.Formula: C16H18FN3O3

Effective norfloxacin elimination via photo-Fenton process over the MIL-101(Fe)-NH2 immobilized on α-Al2O3 shee was written by Zhao, Qian;Wang, Chong-Chen;Wang, Peng. And the article was included in Chinese Chemical Letters in 2022.Formula: C16H18FN3O3 The following contents are mentioned in the article:

MIL-101(Fe)-NH2@Al2O3 (MA) catalysts were successfully synthesized by reactive seeding (RS) method on α-Al2O3 substrate, which demonstrated excellent photo-Fenton degradation performance toward fluoroquinolone antibiotics (i.e., norfloxacin, ciprofloxacin, and enrofloxacin). The structure and morphol. of the obtained MA were characterized by transmission electron microscopy (TEM), high-resolution transmission electron microscopy (HRTEM), at. force microscope (AFM). The as-prepared MA could accomplish > 90% of norfloxacin degradation efficiency for 10 cycles’ photo-Fenton processes, owing to its excellent chem. and water stability. In addition, the effects of operational factors including H2O2 concentration, foreign ions, and pH on the photo-Fenton degradation of norfloxacin over MA were clarified. The ESR spectra further document that ·O2–, 1O2 and ·OH radicals are prominent in the decomposition process of antibiotic mols. Finally, the plausible photo-Fenton norfloxacin degradation mechanisms were proposed and verified. This study involved multiple reactions and reactants, such as 1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7Formula: C16H18FN3O3).
