Optimization of H2O2 use during the photocatalytic degradation of ethidium bromide with TiO2 and iron-doped TiO2 catalysts

▶ EtBr is eliminated by heterogenous photocatalysis with TiO2 and iron-doped TiO2. ▶ Acid/basic properties affected by iron presence are essential to EtBr photodegradation. ▶ Optimization of the use of H2O2 improves the properties for complete mineralization of EtBr.
