Summary: Antibiotics pose a growing environmental challenge due to their mutagenic and persistent effects. In this study, y-Fe2O3 and ferrites nanocomposites co-modified carbon nanotubes were synthesized for the removal of ciprofloxacin. The adsorption capacities of ciprofloxacin on y-Fe2O3/MFe2O4/CNTs were determined to be 44.54 (Co), 41.13 (Cu), and 41.53 (Mn) mg/g. The adsorption mechanisms were explored and the role of magnetic substances in the adsorption process was revealed. This research provides insights for the development of similar adsorbents for environmental applications.

Summary: La2S3/SN-biochar composites were prepared by modifying S,N-codoped biochar with La2S3, which significantly improved the adsorption and photocatalytic activities for tetracycline hydrochloride removal. The optimal 3c-La2S3/SN-biochar with a La content of 15.43 wt% and an N content of 0.49 wt% exhibited the highest TCH removal efficiency. However, long-term photo-corrosion led to decreased adsorption-photocatalytic efficiency and decreased adsorption capacity.

Summary: A composite of diatomite and basic zinc chloride was prepared using a straightforward deposition method, and it showed highly efficient removal of ciprofloxacin. The optimized composite had a ciprofloxacin adsorption capacity of 831.96 mg/g, broad pH adaptability, rapid adsorption rate, and stable performance under Na+ ionic strength. The high adsorption capacity can be attributed to electrostatic attraction, hydrogen bonding, surface complexation, and available adsorption sites.

Summary: In this investigation, cyclopentyl methyl ether (CMPE) was explored as a new membrane solvent for the removal of acetic acid from an aqueous medium using facilitated bulk liquid membrane (BLM). Tributyl phosphate (TBP) was used as a carrier in CMPE to enhance the transport of acetic acid. The effects of various operating factors such as carrier concentration, receiving phase type, and receiving phase concentration on the removal were analyzed. The uptake was evaluated through extraction and receiving yields. A mass transfer modeling was established, and the mass transfer coefficients were determined. The highest yields were achieved with 95.4% extraction and 78.01% receiving yields at a carrier concentration of 2 mol/L in the membrane solvent and a receiving phase concentration of 4 mol/L NaOH.
