The sodium salt form of cefuroxime and a semi-synthetic, broad-spectrum, beta-lactamase resistant, second-generation cephalosporin antibiotic with bactericidal activity. Cefuroxime sodium inhibits bacterial cell wall synthesis by inactivating penicillin binding proteins (PBPs) thereby interfering with the final transpeptidation step required for cross-linking of peptidoglycan units which are a component of the cell wall. Lack of cross-linking results in a reduction of cell wall stability and leads to cell lysis.
A method for treating cefuroxime sodium production wastewater
The present application relates to the technical field of pharmaceutical wastewater treatment, and relates to a treatment method of cefuroxime sodium production wastewater. First, the cefuroxime sodium production wastewater is pretreated, and the pH is adjusted to 5.0-7.5; the porous magnetic catalytic aerogel is put into the pretreated wastewater, and mixed treatment is carried out while sunlight irradiation; the porous magnetic catalytic aerogel is taken out, and the treated water is obtained. The 24-hour degradation rate of the cefuroxime sodium and cefuroxime axetil can reach more than 95%, and the COD removal rate is more than 90%. The present application realizes the efficient degradation treatment of antibiotics and organic matters in the cefuroxime sodium production wastewater by using visible light catalysis and through the synergistic mechanism of 'adsorption-enrichment-degradation'.
