“…40 Recent studies have shown that the dissipation in the environment of organic contaminants such as veterinary antibiotics can occurred via abiotic and biotic processes. 41,42 Nevertheless, several studies also revealed the presence of numerous veterinary antibiotic residue classes in surface waters and ground waters close to agricultural areas. 41,43,44 The analysis of 39 groundwater samples taken in seven different groundwater bodies of Catalonia under a relevant agricultural pressure revealed the presence of at least 15 different sulfonamides in concentration up to 274 ng L -1 , but SCP was not determined.…”

“…Adsorption mechanism of antibiotics in soil was mainly due to charge transfer and ion interactions, and was significantly influenced by the pH of the soil (Thiele-Bruhn 2003;Tolls 2001). Antibiotics were susceptible to microbial degradation under aerobic conditions (Pan and Chu 2016).…”

Antibiotics can accumulate in soils via different ways, which may pose serious threat to ecological environment of soil and quality of agricultural products. In this study, the occurrence of 12 antibiotics including four sulfonamides (SAs), four tetracyclines (TETs) and four fluoroquinolones (FQs) was investigated in soils from four sampling sites of Kenya (Mai Mahiu, Narok, Mount Suswa Conservancy, and Juja), Africa. The soils in suburban area of Narok had the highest average concentrations of total 12 antibiotics with an average value of 43.64 μg kg(-1) dw (dry weight), followed by Mai Mahiu (26.70 μg kg(-1) dw), Juja (24.41 μg kg(-1) dw) and Mount Suswa Conservancy (12.21 μg kg(-1) dw). Sulfamethoxazole, sulfamethazine, oxytetracycline, and enrofloxacin were identified as the main antibiotics polluted in soils. Total organic carbon may influence the distribution of SAs in Narok and FQs in Juja. Ecological risk analysis based on the risk quotient showed that SAs detected in soils have higher risk compared to TETs and FQs.

“…Sulfonamide is a pharmaceutically active compound (PhAC) that is often detected in wastewater. 1 The ubiquitous existence of sulfonamide in aquatic environments has received increasing attention in recent years because it can have an antibiotic effect. 2 However, it cannot be removed effectively using conventional wastewater treatment processes.…”

“…However, the catalytic activity of these heterogeneous catalysts is not very high because the reaction rate constant k of reaction (2) is 0.001-0.01 M −1 s −1 , leading to reaction (2) being much slower than reaction (1). Recently, many studies have focused on how to accelerate the reduction of Fe(III) to Fe (II), so that ferromagnetic catalytic activity can be improved, for example, surface properties, 13 particle size, shape, surface structure as well as composition.…”

BACKGROUND The presence of sulfonamide antibiotics in aquatic environments has received increasing attention. In this study, the nanocomposite Fe3O4–Mn3O4 was synthesized, characterized and used as a catalyst for the degradation of sulfamethazine (SMT) in a heterogeneous Fenton‐like process. RESULTS The composites were characterized by X‐ray diffraction (XRD), transmission electron microscopy (TEM), X‐ray photoelectron spectroscopy (XPS), BET specific surface area, vibrating sample spectrometry (VSM), Raman and Fourier transform infrared (FTIR) spectroscopy before and after use. The catalytic activity was evaluated under different conditions, including pH value, H2O2 dosage, catalyst dosage, temperature and initial concentration of SMT. The removal efficiency of SMT was more than 99% in 50 min at pH=3, T = 45 °C, H2O2=6 mmol L−1, Fe3O4–Mn3O4 dosage = 0.5 g L−1, SMT=20 mg L−1. CONCLUSIONS Fe3O4–Mn3O4 composite was an efficient catalyst for degradation of SMT in a Fenton‐like process. © 2016 Society of Chemical Industry
