Selective adsorption of tetracycline and copper(II) on ion-imprinted porous alginate microspheres: performance and potential mechanisms
Environ Sci Pollut Res Int. 2023 Sep 16. doi: 10.1007/s11356-023-29810-0. Online ahead of print.ABSTRACTA novel epichlorohydrin and thiourea grafted porous alginate adsorbent (UA-Ca/IIP) was synthesized using ion-imprinting and direct templating to remove copper ions (Cu(II)) and tetracycline (TC) in aqueous solution. UA-Ca/IIP demonstrated great selectivity for Cu(II) and TC among different coexisting anions (CO32-, PO43- and SO42-), cations (Ca2+, Mg2+ and NH4+), and antibiotics (oxytetracycline and sulfamethoxazole). The adsorption of TC and Cu(II) by UA-Ca/IIP was significantly affected by the pH of the solution, and t...

Bioaccessibility of polypropylene microfiber-associated tetracycline and ciprofloxacin in simulated human gastrointestinal fluids
This study investigated the mechanism and primary factor controlling the bioaccessibility of polypropylene (PP) microplastic fiber-associated tetracycline (TC) and ciprofloxacin (CIP) in simulated human gastrointestinal fluids. After mixing 0.1 g of PP microfiber with 10 mg/L of TC (or CIP) for 96 h and exposure to simulated human gastrointestinal fluids, the TC concentrations were 0.440, 0.678, and 1.840 mg/L and the CIP concentrations were 0.700, 1.367, and 3.281 mg/L CIP in the simulated human saliva, gastric, and intestinal fluids after incubation for 60 s, 4 h, and 8 h, respectively. This indicated that the antibiotic...

Preparation of sludge-based biochar loaded with ferromanganese and its removal mechanism of tetracycline hydrochloride
Environ Sci Pollut Res Int. 2023 Aug 30. doi: 10.1007/s11356-023-29558-7. Online ahead of print.ABSTRACTTo remove the serious contamination caused by tetracycline hydrochloride, this paper uses the method of impregnation followed by pyrolysis to prepare ferromanganese-loaded sludge-based biochar and investigate its effectiveness in removing tetracycline hydrochloride. The material was characterized by field emission SEM, FTIR, and X-ray diffraction analysis. The possible reaction mechanisms involved in the removal of tetracycline were deduced based on the determination of Mn2+ during the reaction process and XPS characteri...

TET-Yeasate: An engineered yeast whole-cell lysate-based approach for high performance tetracycline degradation
Environ Int. 2023 Aug 17;179:108158. doi: 10.1016/j.envint.2023.108158. Online ahead of print.ABSTRACTThe widespread of tetracycline (TC) residues in anthropogenic and natural environments pose an immediate threat to public health. Herein, we established the TET-Yeasate, an approach based on whole-cell lysate of engineered yeast, to mitigate the TC contamination in environment. The TET-Yeasate is defined as the biological matrix of whole cell lysate from engineered yeast that containing TC-degradative components (Tet(X), NADPH, Mg2+) and protective macromolecules. The TET-Yeasate was able to efficiently eliminate TC residu...

Tetracycline-adsorbed biochar for solid biofuel usage to achieve waste utilization for environmental sustainability
This study explored the potential of biochar for the adsorption of an aquatic organic pollutant (tetracycline) and its subsequent use as a solid biofuel. These results suggest that corn straw-derived biochar (torrefaction and pyrolysis) is suitable for two-stage utilization to achieve bioresource valorization for environmental sustainability. Tetracycline-adsorbed biochar, particularly biochar pyrolyzed at 600 °C, is suitable for use as a biofuel. The biochar produced via torrefaction (300 °C) and pyrolysis (600 °C) is the optimal choice, with surface area, contact angle, graphitization degree, calorific value, enhancem...

A co-precipitation route for the preparation of eco-friendly Cu-Al-layered double hydroxides with efficient tetracycline degradation
Environ Sci Pollut Res Int. 2023 Aug 23. doi: 10.1007/s11356-023-29345-4. Online ahead of print.ABSTRACTThe construction of novel efficient catalysts for the treatment of organic pollutants in the aqueous environment is essential. The lamellar-like Cu-Al layered double hydroxides (CuAl-LDHs) with various mole ratios were synthesized by a simple route of co-precipitation, and the corresponding degradation characteristic was tested for the removal of tetracycline (TC) using PMS activation. The degradation efficiency of TC over CuAl-LDHs increased up to 93% within 10 min for the Cu/Al mole ratio of 3:1 and almost not changed ...

Heterojunction photocatalyst FeS < sub > 2 < /sub > /g-C < sub > 3 < /sub > N < sub > 5 < /sub > for activating sulfites to degrade tetracycline: A stable degradation system based on heterogeneous processes
Environ Res. 2023 Aug 21:116939. doi: 10.1016/j.envres.2023.116939. Online ahead of print.ABSTRACTThe UV/sulfite system is a promising source of •SO4- and/or •OH, but its application is largely limited by the use of UV light due to its high cost and high energy consumption. Graphite carbon nitride (g-C3N5), as a new photocatalytic material, has better visible light absorption capacity and narrower band gap than g-C3N4, which is expected to activate sulfite under visible light to solve this problem. Herein, a novel FeS2/CN heterojunction material based on g-C3N5 was constructed by hydrothermal in-situ synthesis method a...

Effects of the coexistence of antibiotics and heavy metals on the fate of antibiotic resistance genes in chicken manure and surrounding soils
This study examined how breeding cycles affect antibiotic resistance genes (ARGs) in chicken manure and the surrounding topsoils at 20, 50, 100, 200, and 300 m from twelve typical laying hen farms in the Ningxia Hui Autonomous Region of northwest China. Six antibiotics, seven heavy metals, ten mobile genetic elements (MGEs), and microbial community affected the ARGs profile in chicken dung and soil samples. Tetracycline antibiotic residues were prevalent in chicken manure, as were relatively high content of aureomycin during each culture period. Zinc (Zn) content was highest among the seven heavy metals in chicken feces. C...

Construction of urchin-like core-shell Fe/Fe < sub > 2 < /sub > O < sub > 3 < /sub > @UiO-66 hybrid for effective tetracycline reduction and photocatalytic oxidation
Environ Pollut. 2023 Aug 11:122280. doi: 10.1016/j.envpol.2023.122280. Online ahead of print.ABSTRACTAlthough Fe/Fe2O3 has potential application compared with nanoscale zero-valent iron (nZVI), its smooth structure largely limits the catalytic performance. To address this challenge, we innovatively constructed highly efficient composite Fe/Fe2O3@UiO-66 via employing an urchin-like core-shell structure of Fe/Fe2O3 onto UiO-66 through a facile ion exchange precipitation method without inert gas protection. The characterization results show the urchin-like core-shell configuration can extend the life span of Fe0 and produce m...
