TL;DR: The reaction product showed to be very stable for samples of peroxide concentrations up to 3mmolL(-1) at room temperature during 180h, and when compared to iodometric titration, the vanadate method showed a good agreament.

TL;DR: In this work, the photocatalytic degradation of the antibiotic sulfamethoxazole (SMX) by solar photo-Fenton at pilot plant scale was evaluated in distilled water (DW) and in seawater (SW).

TL;DR: Different pathways of AMX degradation were suggested including the opening of the four-membered β-lactamic ring and further oxidations of the methyl group to aldehyde and/or hydroxylation of the benzoic ring, generating other intermediates after bound cleavage between different atoms and further oxidation to carboxylates such acetate, oxalate and propionate.

TL;DR: Daphnia magna was the most sensitive showing an increase from 60% to 100% immobilization after 30 h of irradiation when depletion of SMX was achieved, thus indicating the higher toxicity of the phototransformation products generated.

TL;DR: In this article, the degradation of the antibiotic tetracycline (TC) by the photo-Fenton process was evaluated under black-light and solar irradiation, and the influences of iron source (Fe(NO3)3 or ferrioxalate), hydrogen peroxide and matrix (pure water, surface water and a sewage treatment plant effluent) were evaluated.
