Simultaneous degradation of ciprofloxacin, amoxicillin, sulfathiazole and sulfamethazine, and disinfection of hospital effluent after biological treatment via photo-Fenton process under ultraviolet germicidal irradiation
(2018-05-01)
A UVC-assisted photo-Fenton process was applied to hospital wastewater that had been submitted to anaerobic treatment. Low iron (10 μM; 0.56 mg L−1) and H2O2 (500 μM; 17 mg L−1) concentrations were used at the natural pH ...
Validation of a liquid chromatography with ultraviolet detection methodology for the determination of sulfonamides in bovine milk according to 2002/657/EC

An eco-friendly method for analysis of sulfonamides in water samples using a multi-pumping system
(2016-08-05)
A new methodology for determination of sulfonamides (sulfaquinoxaline, sulfathiazole, and sulfadimethoxine) in water samples was developed by coupling an automated multi-pumping flow system (MPFS) with a liquid waveguide ...
Multiscreening LC-MS/MS designed for ten pesticide and six antimicrobial residues in eggs
(2017-01-01)
A multiscreening method was experimentally validated for pesticide and antimicrobial residues in spiked eggs at levels of 5, 50, and 500 μgL−1. The residue extraction was performed with acetonitrile and 1% formic acid. The ...
Parameters affecting sulfonamide photo-Fenton degradation - Iron complexation and substituent group
(Elsevier B.V. Sa, 2012-03-15)
The photo-Fenton degradation of the sulfonamide antibiotics sulfadiazine (SDZ) and sulfathiazole (STZ) mediated by Fe(III)-oxalate was studied in this work. The influence of iron complexation. H2O2 concentration and pH on ...
Nontronite mineral clay NAu-2 as support for hematite applied as catalyst for heterogeneous photo-Fenton processes
(2021-08-01)
This study describes the characterization of Nontronite, a clay mineral with high content of structural iron, before and after iron incorporation and 600 °C heat treatment. The Nontronite was classified as a mesoporous ...
