Abstract:The effect of oxalate on the degradation of ranitidine was investigated in the titanium dioxide (TiO2)/hydrogen peroxide (H2O2) system. The degradation of ranitidine proceeded more rapidly, with a 5.7-fold increase in the presence of oxalate. The oxalate-enhanced degradation is attributed to the higher production of hydroperoxyl radicals (HO2 ●) through the complexation of oxalate on the >TiIII (>TiIII(oxalate)n (2n−3)−), generated from inner-sphere electron transfer in the peroxo metal complexes (>Ti… Show more
