Background: As one of the modal antibiotics in life, the abuse of tetracycline (TC) caused great risks to the ecological environment and health. Cost-effective removal method of TC in the medical wastewater was a developmental research direction with great potential.Results: In this work, a novel material, modified kaolin/β-cyclodextrin (β-CD) coated A (A is a special oxidant made from our laboratory, which is mainly composed of potassium ferrate) was synthesized and characterized. Meanwhile, the removal efficiencies and influencing factors of TC in novel material activation reaction systems were systematically studied. The specific surface area of modified kaolin (MMK) can reach up to 431.82 m 2 /g after acid and calcination modification. The results of SEM, TEM, XRD, and FT-IR showed the significant increase in specific surface area of MMK was the complete destruction of kaolin structure and the leaching of aluminum. β-CD was selected to coat A to attenuate the rapid release of A in water. The optimal coat molar ratio of β-CD and A was 10: 1 (β-CD:A). MMK/β-CD-A was used to treat the simulated TC wastewater, the removal efficiency was 95.6 % within 90 min when the concentration of TC was 0.22 mmol/L. The removal mechanism of TC with MMK/β-CD-A was the adsorption effect from MMK and the oxidation effect from β-CD-A. Conclusion:This work could provide useful information for developing a simple and effective technology to treat TC in medical wastewater.

“…It was reported that Kar et al [ 134 ] constructed heterojunctions (Fe 2 O 3 @BC) on ACFs, which could exhibit excellent photocatalytic activities for the degradation of antibiotics under visible light. Furthermore, Jiang et al [ 135 ] deposited spinel-type CoFe 2 O 4 on ACFs. Due to the synergistic interaction between CoFe 2 O 4 and ACFs, ACF/CoFe 2 O 4 could effectively remove the pesticide pollutant atrazine (ATZ) by adsorption and photo-Fenton degradation.…”

Driven by various environmental and economic factors, it is emerging to adopt an efficient and sustainable strategy to recycle carbon fibers (rCFs) from carbon fiber-reinforced polymer (CFRP) wastes and reuse them in high-value applications. This review summarized the latest progress of CFRP waste recycling methods (including mechanical, chemical, and thermal methods), discussed their advantages and disadvantages, influence parameters and possible environmental effects, and their potential effects on the mechanical and surface chemical properties of rCFs. In addition, the latest optimization schemes of leading recycling technologies were detailed. According to the literature, CFs are the key points in the structural support of semiconductor-based recyclable photocatalytic systems and the enhancement of performance, which means that rCFs have high reuse potential in sustainable photocatalysis. Therefore, this paper also emphasized the possibility and potential value of reusing recovered fibers for developing recyclable photocatalytic products, which may be a new way of reuse in environmental purification often ignored by researchers and decision-makers in the field of CFs.

The harm and treatment of methyl blue (MB) were described, and the necessity for the removal of MB by magnetic nanomaterials was explained. Magnetic Ni-Mg-Co ferrites were prepared by the rapid combustion approach of an active nitrate solution and characterized by X-ray diffraction (XRD), scanning electron microscope (SEM), Fourier transform infrared spectrometer (FTIR), energy dispersive spectroscopy, and vibrating sample magnetometer. Magnetic Ni 0.1 Mg 0.7 Co 0.2 Fe 2 O 4 nanoparticles prepared at 400 C with the saturation magnetization of 19.7 emu g À1 and the average diameter of about 15.2 nm were used to adsorb MB from the aqueous medium. The Brunauer-Emmett-Teller (BET) analysis showed that the specific surface area was 143.17 m 2 g À1 and the average pore size was 9.44 nm. The adsorption mechanism of MB onto magnetic Ni 0.1 Mg 0.7 Co 0.2 Fe 2 O 4 nanoparticles was studied, and the results revealed that the adsorption properties conformed the pseudo-second-order kinetics model due to the square deviation values (R 2 > 0.98), and Temkin model could describe the adsorption state of MB onto Ni 0.1 Mg 0.7 Co 0.2 Fe 2 O 4 nanoparticles, which suggested that the adsorption of MB onto Ni 0.1 Mg 0.7 Co 0.2 Fe 2 O 4 nanoparticles was monolayer-multilayer hybrid chemisorption mechanism. When the pH value exceeded 3, the adsorbance reached large value; while, the adsorbance was 97.6% of the initial adsorption value for seven cycles. The electrochemical impedance spectroscopy and cyclic voltammetry curves of MB adsorbed onto the nanoparticles before and after the adsorption were determined.
