“…Most of the previous studies on antibiotics conducted qualitative and quantitative analyses of antibiotics. Antibiotics are detected using traditional detection technologies, such as chromatography and its combined technology [4], capillary electrophoresis [5], immunochromatography [6], and microbiology techniques [7]. As shown in Table 1, these methods can achieve satisfactory sensitivity and accuracy.…”

Antibiotics, as veterinary drugs, have made extremely important contributions to disease prevention and treatment in the animal breeding industry. However, the accumulation of antibiotics in animal food due to their overuse during animal feeding is a frequent occurrence, which in turn would cause serious harm to public health when they are consumed by humans. Antibiotic residues in food have become one of the central issues in global food safety. As a safety measure, rapid and effective analytical approaches for detecting these residues must be implemented to prevent contaminated products from reaching the consumers. Traditional analytical methods, such as liquid chromatography, liquid chromatography mass spectrometry, and capillary electrophoresis, involve time-consuming sample preparation and complicated operation and require expensive instrumentation. By comparison, surface-enhanced Raman spectroscopy (SERS) has excellent sensitivity and remarkably enhanced target recognition. Thus, SERS has become a promising alternative analytical method for detecting antibiotic residues, as it can provide an ultrasensitive fingerprint spectrum for the rapid and noninvasive detection of trace analytes. In this study, we comprehensively review the recent progress and advances that have been achieved in the use of SERS in antibiotic residue detection. We introduce and discuss the basic principles of SERS. We then present the prospects and challenges in the use of SERS in the detection of antibiotics in food. Finally, we summarize and discuss the current problems and future trends in the detection of antibiotics in food.

“…A to produce large amounts of ozone with the MIKROZON® cell that assure the disinfection process in absence of chlorides. Finally, urine contains organic compounds which can be also oxidized during the electrolysis: urea, creatinine and uric acid [45]. The degradation of these organics can compete with the disinfection process and, for this reason, their concentrations were analyzed.…”

“…Results showed that pharmaceutical abatement rates were greater than 50% after 120 min of electrolysis when applying 35.4 mA cm −2 . More recently, Herraiz-Carboné et al [90] compared the use of active and non-active anodes for the removal of 100 mg dm −3 chloramphenicol in urine. They concluded that it was possible to attain a complete antibiotic removal when working with BDD anodes for all the current densities tested (1.25-5 mA cm −2 ) whereas the use of anodes based on mixed metal oxides (MMO) led to removal percentages of around 25% under the same operating conditions (Figure 8).…”

The inefficiency of conventional biological processes to remove pharmaceutical compounds (PhCs) in wastewater is leading to their accumulation in aquatic environments. These compounds are characterized by high toxicity, high antibiotic activity and low biodegradability, and their presence is causing serious environmental risks. Because much of the PhCs consumed by humans are excreted in the urine, hospital effluents have been considered one of the main routes of entry of PhCs into the environment. In this work, a critical review of the technologies employed for the removal of PhCs in hospital wastewater was carried out. This review provides an overview of the current state of the developed technologies for decreasing the chemical risks associated with the presence of PhCs in hospital wastewater or urine in the last years, including conventional treatments (filtration, adsorption, or biological processes), advanced oxidation processes (AOPs) and electrochemical advanced oxidation processes (EAOPs).
