Developing efficient photocatalysts based on the peroxymonosulfate (PMS) activation for effective degradation of threatening antibiotic contamination under visible light is still a challenging subject. Herein, a Co-doped Bi2MoO6 (CBMO) spherical crystals were synthesized via a facile hydrothermal method and used to degrade artificial antibiotic wastewater via PMS activation under visible light. The obtained 3 wt% Co-doped Bi2MoO6 (3CBMO) can effectively remove 98.95% of norfloxacin (NOF) within 40 min, 100% of tetracycline (TC) and metronidazole (MNZ) within 30 min. Compared with the contrasting catalysts, the superior catalytic activity of 3CBMO was attributed to the synergistic effect of photocatalytic and Co(II) activated PMS degradations Quenching tests in combination with EPR measurements revealed that the hole (h+), sulfate (SO-4•) and hydroxyl (•OH) were the primary radicals all contributed to NOF degradation The influences of initial concentration, catalyst dosage, PMS dosage and various interfering ions (NO-3, Cl–, SO2-4, and HCO-3) on the degradation efficiency of NOF were systematically examined Furthermore, possible degradation pathways of NOF were proposed by LC-MS. This novel 3CBMO catalyst might be a promising candidate for degradation of the main sources of antibiotic contamination in pharmaceutical wastewater. 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: 70458-96-7Product Details of 70458-96-7).
1-Ethyl-6-fluoro-4-oxo-7-(piperazin-1-yl)-1,4-dihydroquinoline-3-carboxylic acid (cas: 70458-96-7) belongs to piperazine derivatives. Simple N-substituted piperazines have been found in many drug molecules. Although many piperazine derivatives occur naturally, piperazine itself can be synthesized by reacting alcoholic ammonia with 1,2-dichloroethane, by the action of sodium and ethylene glycol on ethylene diamine hydrochloride, or by reduction of pyrazine with sodium in ethanol.Product Details of 70458-96-7
