Efficient degradation of ciprofloxacin by photocatalytic activity of Ag-modified ZnO

Ciprofloxacin (CIP) is a highly persistent antibiotic whose presence in natural aquatic matrices represents a critical challenge for public health and environmental protection. In this study, the photocatalytic efficiency of ZnO and its Ag-modified counterpart, synthesized by coprecipitation and photodeposition, respectively, was evaluated in the ciprofloxacin elimination in distilled water and in a real matrix…

Photo-assisted degradation of rhodamine B with H₂O₂: Kinetics, modern machine learning prediction, and insights into a novel iron oxide catalyst

This study introduces a dual strategy that combines kinetic modeling and advanced machine learning (ML) models to enhance the prediction and optimization of Rhodamine B (RhB) degradation using an H2O2/UV system. As a novel scientific contribution, we report the first-time synthesis of an iron-based catalyst, integrating α-Fe2O3 with structural ions (SO₄2−, OH−, Cl−), synthesized via a…

Upcycling pine-bark into powerful adsorbents: tetracycline removal from aquaculture effluents combining biochar and advanced oxidation processes

The presence of antibiotics in aquaculture wastewater poses environmental and public-health risks by disrupting aquatic ecosystems and promoting the spread of antibiotic-resistant bacteria. This study evaluates pine-bark biochars activated under different atmospheres for the removal of tetracycline from real aquaculture wastewater and examines their combined use with peroxymonosulfate as an oxidant. The biochars were produced…

AgBr and Ag3PO4 Coupled with TiO2 as Active Powder Photocatalysts and Glass Coatings

  In this work, different materials based on TiO2 coupled with either AgBr or Ag3PO4 were synthesized. The Ag3PO4(50%)/TiO2 powder photocatalyst prepared by deposition-precipitation method showed higher antimicrobial activity than the bare TiO2 and also than the same coupled powder obtained by sol-gel method. This material achieved 100% E. coli, coliforms, and other enterobacteria elimination.…
