“…As a traditional synthetic class of antibacterial drugs, sulfonamide antibiotics are broadly employed in aquaculture and animal husbandry because of their cheap and chemical stability. [139,140] Sulfonamides have a broad antibacterial spectrum and inhibit most Gram-positive and negative bacteria. SA have stable physicochemical properties and easily accumulate in the environment once they are released into the environment.…”

Antibiotics cause negative impacts on the ecosystem and people‘s health, and it is imperative to reduce antibiotic residuum in a green and sustainable way. There has been a broad application of photocatalytic technology in the sewage treatment field. Compared with metal oxides, graphite carbon nitride, as an n‐type non‐metallic semiconducting polymer, has an applicable energy gap, simple preparation and easily accessible. Yet the g‐C3N4 of simple preparation tends to have some crucial weaknesses like rapid charge carrier recombination, underutilization of the visible spectrum and incomplete mineralization, which severely confine its farther application. Element doping modification enormously improves the separation of g‐C3N4 photogenic hole‐charge, which is applied to the removal of antibiotics in wastewater. The doping modification of g‐C3N4‐based semiconductor photocatalysts and research progress in the photocatalytic degradation of various antibiotics (sulfonamides, β‐lactam, quinolones, tetracycline) in water are reviewed in this paper, and the preparation of g‐C3N4, the sorts and principles of elemental doping are investigated, with emphasis on the application of g‐C3N4 towards the photocatalytic degradation of antibiotics, and the existing problems and challenges in this field are put forward.

The continuous introduction of micropollutants into the environment through livestock farming, agricultural practices, and wastewater treatment is a major concern. Among these pollutants are synthetic sulfonamide antibiotics such as sulfamethoxazole, which are not always fully degraded and pose a risk of fostering antimicrobial resistance. It is challenging to assess the degradation of sulfonamides with conventional concentration measurements. This study introduces compound-specific isotope analysis of nitrogen isotope ratios at natural abundances by derivatization-gas chromatography hyphenated with isotope ratio mass spectrometry (derivatization-GC-IRMS) as a new and more precise method for tracing the origin and degradation of sulfonamides. Here, sulfamethoxazole was used as a model compound to develop and optimize the derivatization conditions using (trimethylsilyl)diazomethane as a derivatization reagent. With the optimized conditions, accurate and reproducible δ15N analysis of sulfamethoxazole by derivatization-GC-IRMS was achieved in two different laboratories with a limit for precise isotope analysis of 3 nmol N on column, corresponding to 0.253 µg non-derivatized SMX. Application of the method to four further sulfonamides, sulfadiazine, sulfadimethoxine, sulfadimidine, and sulfathiazole, shows the versatility of the developed method. Its benefit was demonstrated in a first application, highlighting the possibility of distinguishing sulfamethoxazole from different suppliers and pharmaceutical products. Graphical Abstract
