Insight into the removal of tetracycline-resistant bacteria and resistance genes from mariculture wastewater by ultraviolet/persulfate advanced oxidation process

Polyethyleneimine-Sulfur Quantum Dot Composites for Dual-Channel Detection of Tetracycline by Colorimetric and Fluorescence Sensing

“…1,2 However, the excessive abuse of TC aggravates the evolution of drug resistance and also poses a great risk to the ecological environment after discharged wastewater treatment. 3,4 The current detection methods of TC usually include HPLC, capillary electrophoresis, and electrochemistry. 5−7 Considering the experimental cost and the environmental contamination from a large volume of organic mobile phase of HPLC, as well as the poor reproducibility of electrochemistry, the fluorescent sensor is definitely the most promising detection method because of its convenience of operation and speed of detection.…”

“…As a broad-spectrum antibiotic, tetracycline (TC) is often used for clinical treatment, forestry, and animal husbandry, as well as animal medication. , However, the excessive abuse of TC aggravates the evolution of drug resistance and also poses a great risk to the ecological environment after discharged wastewater treatment. , The current detection methods of TC usually include HPLC, capillary electrophoresis, and electrochemistry. − Considering the experimental cost and the environmental contamination from a large volume of organic mobile phase of HPLC, as well as the poor reproducibility of electrochemistry, the fluorescent sensor is definitely the most promising detection method because of its convenience of operation and speed of detection . A variety of fluorescent sensors for the detection of TC have been reported, most of which are based on carbon quantum dots doped with N and S atoms. , These carbon dots have excitation-dependent fluorescence, which may be important for certain practical applications, but their relatively poor color purity and broad emission spectra seriously limited their practical application. , …”

Alkali-Activated Potassium Persulfate Treatment of Sugarcane Filter Cake for the Rapid Production of Fulvic-like-Acid Fertilizer

“…In the AOPs, the free radicals are strong oxidants and could enhance the composting process (i.e., Le Chatelier’s principle). At the same time, the macromolecular substances in the SFC could be rapidly decomposed to produce small molecular substances and most of the harmful bacteria are eliminated. , Because the composition (carboxylic acid, amino acids, quinones, and aromatic hydroxyl) and properties of small molecular substances are similar to those of fulvic acid (FA), they are named fulvic-like acid (FLA) . Meanwhile, the abundant FLA could meet the needs of plants and reduce the activity of heavy metals (HMs) in SFC .…”

“…Among AOPs, potassium peroxydisulfate (PS) is investigated widely because it can produce sulfate radicals (SO 4 •– ), which have a high oxidative power and long half-life . Typically, PS could be activated by various types of activators, such as metal ions, metal oxides, carbon materials, ultraviolet irradiation, and thermal activation . Due to the complex activated process and high-cost limitations, a kind of new activated process for PS in SFC is quite necessary.…”

Sulfadiazine Elimination from Wastewater Effluents under Ozone-Based Catalysis Processes

“…Antibiotics and other drugs can be directly oxidatively removed by PMS and PS; nevertheless, their reaction rate is very low [29][30][31][32]. PMS and PS can be activated by photocatalysts, heating and metal ions to produce highly reactive oxygen species (ROS) such as hydroxyl radicals (•OH) and sulfate radicals (SO 4 • − ) [26,[33][34][35][36][37]. According to Feng et al (2017), the catalysis process PMS/Fe (VI) promoted the generation of SO 4 • − and •OH and enhanced the degradation of fluoroquinolones (FQ) [38].…”
