TLDR
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.About:

Facile Photochemical Synthesis of Au/Pt/g-C3N4 with Plasmon-Enhanced Photocatalytic Activity for Antibiotic Degradation
TL;DR: A novel plasmonic photocatalyst, Au/Pt/g-C3N4, was prepared by a facile calcination-photodeposition technique and enhanced photocatalytic activity for antibiotic tetracycline hydrochloride (TC-HCl) degradation was attributed to the surface plAsmon resonance effect of Au and electron-sink function of Pt nanoparticles, synergistically facilitating the photocatalysis process.

A New Sensitive Chemical Actinometer. II. Potassium Ferrioxalate as a Standard Chemical Actinometer
C. G. Hatchard,C. A. Parker +1 more
TL;DR: In this paper, a detailed study has been made of the photolysis of the acidified solutions previously recommended for chemical actinometry, and accurate values of quantum efficiency have been determined at twelve wavelengths between 254 and 578 m$\mu $, and the effect of temperature, light intensity and of photolyte composition have been investigated.

Simple and fast spectrophotometric determination of H(2)O(2) in photo-Fenton reactions using metavanadate.
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.
