“…[41][42][43] Almost 70% of Nor was le in the sludge of biological treatment plants. 41,44 As a result, pathogens become increasingly resistant to the drugs, 43,45,46 posing a great threat to aquatic and terrestrial organisms as well as to humans. Recently, systems of photocatalytic degradation under UV light, [47][48][49] nanoscale zero-valent iron with H 2 O 2 , 50 electro-Fenton treatment, 51 thermally activated persulfate, 52 and gamma-ray irradiation 53 were deployed to remove Nor.…”

“…Several analytical methodologies have been developed for the extraction, isolation, clean-up, and preconcentration of residues of veterinary drugs such as liquid-liquid extraction (LLE) [ 9 ], solid phase extraction (SPE) [ 10 ], solid phase microextraction (SPME) [ 11 ], microwave-assisted extraction (MAE) [ 12 ], and pressurized liquid extraction (PLE) [ 13 ]. However, the use of these techniques in some cases require additional pretreatments or specific manipulations.…”

To achieve analytical success, it is necessary to develop thorough clean-up procedures to extract analytes from the matrix. Dispersive solid phase extraction (DSPE) has been used as a pretreatment technique for the analysis of several compounds. This technique is based on the dispersion of a solid sorbent in liquid samples in the extraction isolation and clean-up of different analytes from complex matrices. DSPE has found a wide range of applications in several fields, and it is considered to be a selective, robust, and versatile technique. The applications of dispersive techniques in the analysis of veterinary drugs in different matrices involve magnetic sorbents, molecularly imprinted polymers, carbon-based nanomaterials, and the Quick, Easy, Cheap, Effective, Rugged, and Safe (QuEChERS) method. Techniques based on DSPE permit minimization of additional steps such as precipitation, centrifugation, and filtration, which decreases the manipulation of the sample. In this review, we describe the main procedures used for synthesis, characterization, and application of this pretreatment technique and how it has been applied to food analysis.

“…Particularly, flumequine (FLU) is one of the most used FQs in intensive aquaculture. Since FLU is difficult to be biodegradable naturally [7,8], it remains active in sediments for extended time periods, producing negative environmental impacts. FLU has been extensively found in surface water and municipal wastewater (2.5-50 ng L -1 ) and in soil (6.9 mg g -1 ) [9][10][11][12][13].…”

Flumequine (FLU) is one of the most used fluoroquinolone antibiotics in intensive aquaculture, however, it has become a typical pollutant in water environment at present due to inappropriate use. Therefore, it is necessary to develop facile techniques for efficient degradation of FLU. In this work, three N-doped TiO2 photocatalysts were synthesized for degradation of FLU. The obtained photocatalysts were characterized using scanning electron microscopy (SEM), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Raman spectrum and UV-Vis diffuse reflection spectra (UV-Vis-DRS). The XRD and XPS results from NH4NO3-doped catalyst (TiO2/AN) confirmed that NO3- ions were successfully incorporated into the lattice of TiO2. The TiO2/AN sample exhibited higher photocatalytic performance than other N-doped catalysts under simulated sunlight irradiation, and 100% removal efficiency of FLU was achieved after 4 hours of illumination. The photogenerated holes (h+) and hydroxyl radicals (•OH) are main reactive species involved in the photocatalytic degradation of FLU. Eight intermediates for photocatalytic degradation of FLU were detected and their toxicities to aquatic organisms were predicted. This study might have important implications for further research on the removal of fluoroquinolone antibiotics in wastewater.
