This study focuses on the photocatalytic degradation of Rhodamine B (RhB) in heterogeneous and homogeneous photo-Fenton reactions. In system, iron(II) doped copper ferrite CuII(x)FeII(1-x)FeIII2O4 nanoparticles (NPs) prepared our previous work were employed as potential catalysts. The photodegradation RhB was carried out a quartz cuvette located diode array spectrometer. experimental conditions...
