“…Immobilized TiO 2 nanobelts modified by Au and CuS nanoparticles (Au–CuS–TiO 2 NBs) displayed a removal efficiency of 96% towards oxytetracycline (OTC) owing to their superior photocatalytic activity [ 57 ]. Graphene oxide (GO) as an efficient adsorbent showed a good removal for TC after 24 h ( R = 96%) [ 58 ]. Powder activated carbon/Fe 3 O 4 magnetic nanoparticles (PAC/Fe 3 O 4 MNPs) were applied as a catalyst to H 2 O 2 -assisted TC degradation, and removal efficiency of 94.5% was obtained [ 59 ].…”

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.

“…In addition to contaminants, industrial wastewater also contains a variety of salts, and the presence of these salts may affect the removal of pollutants [ 3 ]. In this study, the effects of ionic strength on the removal of TC by Fe 3 O 4 @GO were investigated by using a series of TC solutions containing different concentrations of NaCl (0–0.1 M).…”

“…Antibiotics are one of the main PPCPs. Since penicillin was discovered in 1929, antibiotics have been used extensively to improve the health of animals and humans, and antibiotics have also been used as growth promoters for livestock, bees, aquatic products and other aquaculture industries [ 3 , 4 ]. Globally, the average total annual use of antibiotics is approximately 200,000 tons [ 4 , 5 ].…”

A readily separated composite was prepared via direct assembly of Fe3O4 magnetic nanoparticles onto the surface of graphene oxide (GO) (labeled as Fe3O4@GO) and used as an adsorbent for the removal of tetracycline (TC) from wastewater. The effects of external environmental conditions, such as pH, ionic strength, humic acid (HA), TC concentration, and temperature, on the adsorption process were studied. The adsorption data were analyzed by kinetics and isothermal models. The results show that the Fe3O4@GO composite has excellent sorptive properties and can efficiently remove TC. At low pH, the adsorption capacity of Fe3O4@GO toward TC decreases slowly with increasing pH value, while the adsorption capacity decreases rapidly at higher pH values. The ionic strength has insignificant effect on TC adsorption. The presence of HA affects the affinity of Fe3O4@GO to TC. The pseudo-second-order kinetics model and Langmuir model fit the adsorption data well. When the initial concentration of TC is 100 mg/L, a slow adsorption process dominates. Film diffusion is the rate limiting step of the adsorption. Importantly, Fe3O4@GO has good regeneration performance. The above results are of great significance to promote the application of Fe3O4@GO in the treatment of antibiotic wastewater.

“…b-Cyclodextrin-modied magnetic g-CN (Fe 3 O 4 -g-CN@PEI-b-CD) could remove 98% of TC with a maximum adsorption capacity of 833.33 mg g À1 , which is much higher than other carbon-based materials. 84 Thiourea dioxides (TD) are a cheaper and safer alternative for sodium borohydride for reduction of magnetic GO (MGO), and the synthesized TDMGO can remove TC with Q m of 1233.257 mg g À1 at 39.85 C. 85 Polyimide-based CNFs, CNPs, and hydrothermally synthesized CNP nanocomposite were also used to remove TC. The results showed that the synthesized CNPs showed a higher SSA of 3561.59 m 2 g À1 and a larger pore volume of 4.78 cm 3 g À1 with a TC removal capacity of 543.48 mg g À1 .…”
