Oxidation of Tris (2-chloroethyl) phosphate in aqueous solution by UV-activated peroxymonosulfate: Kinetics, water matrix effects, degradation products and reaction pathways.
TLDR
It was found that an increase of the PMS dose and the presence of Fe3+ could accelerate the reaction, while the anions and HA inhibited the reaction and UV/PMS can be used as an efficient technology to treat TCEP-containing water and wastewaters.About:

Influence of pH on the formation of sulfate and hydroxyl radicals in the UV/peroxymonosulfate system.
TL;DR: The formation of HO(•) and SO(4)(•-) in the UV/PMS system was confirmed mainly from the cooperation of the photolysis of PMS, the decay of peroxomonosulfate radical (SO(5)(•-)) and the conversion of SO(3)(•) to HO( •) by simulation and experimental results.
