“…2(B)), showing that the intensity of Mn 3+ increased and that of Mn 4+ decreased after surface adsorption ( Table 1), suggesting that a surface redox reaction between BZA and MCM led to partial reduction of Mn 4+ to Mn 3+ . The oxidation of organic pollutants by MnO 2 has been reported previously [56,57]. Furthermore, three intermediates (B-1, B-2, and B-4) of the oxidation of BZA by Mn 4+ were identified by liquid chromatography-mass spectrometry (LC-MS/MS) in the preadsorption phase (Table S2 and Fig.…”

“…Water pollutants including heavy ions [ 26 ], organic dyes [ 27 ], and phenols [ 28 ] treated by MnO 2 nanomaterials were reported. Meanwhile, antibiotics such as levofloxacin [ 29 ], ciprofloxacin [ 30 ], norfloxacin [ 31 ], sulfamethoxazole [ 32 ], sulfadiazine [ 33 ], cefazolin [ 34 ], lincosamide [ 35 ], and TCs [ 36 , 37 ] have been successfully decontaminated through MnO 2 treatment. Specific to TC antibiotics, highly porous MnO 2 nanosheets were utilized to degrade tetracycline, and pH, temperature, and dose-based kinetics were investigated [ 38 ].…”

Taking advantages of reticular proteins and reductive groups on the surface, eggshell membrane (ESM) was selected to synthesize MnO2 nanoparticles from potassium permanganate through a super simple way in which ESM acted as both template and reductant. This process avoided harsh reaction conditions or complicated aftertreatments and thus owned the merits of green synthesis, handy operation, low cost, and easy purification. The ESM-templated MnO2 nanoparticles (MnO2 NPs/ESM) were characterized, and the content of nanomaterials on the template was tested. MnO2 NPs/ESM showed a good capacity for decontamination of tetracycline hydrochloride (TCH). The macroscopical materials can be separated easily by taking the membrane out to stop the degradation instead of centrifugation or filtration. It was studied that 72.27% of TCH (50 mg/L) was decontaminated in 20 min by 0.1920 g/L MnO2 nanoparticles, and removal efficiency could reach 83.10% after 60 min under buffered condition. The kinetics was studied with or without buffer, and it was concluded that the degradation process followed a pseudo-second-order model. The facile synthesis of materials and effective degradation would facilitate the nano-MnO2-based decontamination applications.Electronic supplementary materialThe online version of this article (10.1186/s11671-018-2679-y) contains supplementary material, which is available to authorized users.

Antibiotic residues have entered into the environment owing to the unreasonable use and disposal of antibiotics. The emergence of antibiotic resistance poses a huge threat to ecosystems and human health. In this study, the network analysis method was used to compare publications on antibiotics in water, soil and sediment from the aspects of countries, institutes, journals, subject categories and keywords based on Web of Science Core Collection. The results indicated that the United States of America and China had dominant positions of studies on antibiotics. The Chinese Academy of Sciences published the most articles on antibiotic research. ‘Chemosphere’, ‘Science of the Total Environment’, ‘Environmental Science and Technology’ and ‘Applied and Environmental Microbiology’ all appeared in the top six journals. ‘Environmental Sciences and Ecology’ was the core subject category of antibiotic research. Further analysis results depicted that ‘Antibiotics’, ‘Tetracycline’ and ‘Antibiotic Resistance’ were found as the research hotspots. Tetracycline and oxytetracycline all showed in the top 50 keywords of antibiotics research in water, soil and sediment. However, chlortetracycline, sulfadiazine and tylosin all emerged only in the top 50 keywords of antibiotics study in soil. In future, more attention should be paid to antibiotic resistance genes and antibiotic resistance bacteria in antibiotics research.
