For the VUV(172 nm) light source, the equilibrium concentration of H2O2 measured in Milli-Q water is more than 50 times higher than that of a low-pressure mercury vapor lamp (UV / VUV(185 nm) despite the fact that the proportion of photon fluxes is only around 5. During UV/VUV(185nm) photolysis of sulfonamides, the contribution of UV(254 nm) is significant tap water had a positive effect in some cases (role of UV254 nm?) Reverse osmosis-treated industrial and biologically treated domestic wastewater had a similar negative effect on UV/VUV(185 nm) photolysis of sulfonamides During VUV(172 nm) photolysis of sulfonamides, clearly biologically treated wastewater reduced the transformation rate the best.
