Journal ArticleDOI

Degradation of highly consumed fluoroquinolones, penicillins and cephalosporins in distilled water and simulated hospital wastewater by UV254 and UV254/persulfate processes.

Efraím A. Serna-Galvis, +3 more
- 01 Oct 2017 - 
TL;DR: To study the participation of direct photolysis and reactive oxygen species (ROS) in photodegradation a model antibiotic of each class (OXA, CPX and CIP) was considered and the applicability of UV254 and UV/PS was assessed using synthetic hospital wastewater.
Journal ArticleDOI

Degradation of seventeen contaminants of emerging concern in municipal wastewater effluents by sonochemical advanced oxidation processes

Efraím A. Serna-Galvis, +6 more
- 01 May 2019 - 
TL;DR: The work demonstrates the high potentiality of the sono-photo-Fenton/oxalic acid system for the pollutants elimination in real-world wastewater matrices.
Journal ArticleDOI

High frequency ultrasound as a selective advanced oxidation process to remove penicillinic antibiotics and eliminate its antimicrobial activity from water.

Efraím A. Serna-Galvis, +4 more
- 01 Jul 2016 - 
TL;DR: Results show that the sonochemical treatment of a penicillinic antibiotic (oxacillin) in simulated pharmaceutical wastewater transformed the initial pollutant into substances that are biotreatable with a typical aerobic biological system.
Journal ArticleDOI

Degradation of the antibiotic oxacillin in water by anodic oxidation with Ti/IrO2 anodes: Evaluation of degradation routes, organic by-products and effects of water matrix components

Ana L. Giraldo, +4 more
- 01 Nov 2015 - 
TL;DR: In this paper, the application of electrochemical anodic oxidation for the removal of the β-lactam antibiotic Oxacillin (OXA) was tested using an undivided stirred tank reactor equipped with a DSA (Ti / IrO 2 ) anode and a zirconium spiral cathode.
Journal ArticleDOI

Comparison of route, mechanism and extent of treatment for the degradation of a β-lactam antibiotic by TiO2 photocatalysis, sonochemistry, electrochemistry and the photo-Fenton system

Efraím A. Serna-Galvis, +4 more
- 15 Jan 2016 - 
TL;DR: In this paper, the degradation of a selected β-lactam antibiotic (oxacillin) by TiO2 photocatalysis, sonochemistry, the photo-Fenton process and electrochemistry (with a Ti/IrO2 anode in sodium chloride) was evaluated.
