  abstract = {{T}his work aims at decontaminating biologically treated domestic wastewater effluents from organic micropollutants by sulfate radical based ({SO}4 center dot-) homogeneous photo-{F}enton involving peroxymonosulfate as an oxidant, ferrous iron ({F}e{II})) as a catalyst and simulated solar irradiation as a light source. {T}his oxidative system was evaluated by using several probe compounds belonging to pesticides (bifenthrin, mesotrione and clothianidin) and pharmaceuticals (diclofenac, sulfamethoxazole and carbamazepine) classes and its kinetic efficiency was compared to that to the well known {UV}-{V}is/{T}i{O}2 heterogeneous photocatalysis. {E}xcept for carbamazepine, apparent kinetic rate constants were always 10 times higher in {PMS}/{F}e({II})/{UV}-{V}is than in {T}i{O}2/{UV}-{V}is system and more than 70% of total organic carbon abatement was reached in less than one hour treatment. {H}ydroxyl radical ({OH}) and {SO}4 center dot- reactivity was investigated using mesotrione as a probe compound through by-products identification by liquid chromatography-high resolution-mass spectrometry and transformation pathways elucidation. {I}n addition to two center dot {OH} based transformation pathways, a specific {SSO}4 center dot- transformation pathway which first involved degradation through one electron transfer oxidation processes followed by decarboxylation were probably responsible for mesotrione degradation kinetic improvement upon {UV}-{V}is/{PMS}/{F}e({II}) system in comparison to {UVV}is/{T}i{O}2 system.},
