Developing green and efficient advanced oxidation technologies is crucial for removing antibiotics from contaminated water environments. Herein, we employed ozone to eliminate tetracycline the water. It was found that micronano bubbles, with a diameter of 0.2–60 μm, exhibited remarkable effectiveness, approximately 90% (10 mM) within mere 20 min. This efficiency 2.2 times higher than achieved by larger bubbles diameters ranging 0.5 4.5 mm. Notably, demonstrated consistent (85%) removal rate across wide pH range (3–11) in presence anions. ability resist environmental interference can be attributed high mass transfer during reaction production large number reactive oxygen species (ROS). discovery has been validated through electron paramagnetic resonance (EPR). Furthermore, high-performance liquid chromatography–mass spectrometry (HPLC–MS) spectrum analysis unveiled degradation pathway. In terms safety, toxicity assessments indicated most resulting byproducts low toxicity. work underscores promising potential as an environmentally friendly approach antibiotic contamination aquatic environment.

Landfills are the primary endpoint for disposal of PFAS-laden waste, which subsequently releases PFAS to surrounding environments through landfill leachate. Ozone foam fractionation emerges as a promising technology removal address issue. This study aims (i) assess effectiveness ozone system remove from leachate, and (ii) quantify equilibrium adsorption onto gas-water interface bubbles, followed by comparison with air fractionation. The results show that is effective more than 90% long-chain removed. identified operating conditions provide valuable insights industrial applications, guiding optimization flow rates (1 L/min), dosing (43 mg/L) minimizing foamate production (4% wettability). modelling reveals surface excess bubbles exceeds 20% - 40% at corresponding concentration. However, overall leachate remains substantial. Notably, generates volumes 2 – 4 times less, resulting in significant cost savings final waste products reduced site storage requirements.
