Influence of pH and salinity on the photocatalytic dye degradation and heavy metal ion reduction with cobalt ferrite photocatalysts

Abstract The magnetic nanoparticle assisted photocatalytic oxidation-reduction is an effective method to remove and detoxify the organic dyes heavy metal ions present in industrial wastewater. In study, degradation of Methyl Orange(MO) dye Cr(VI) presence cobalt ferrite (CoFe 2 O 4 ) superparamagnetic photocatalysts under visible light illumination are investigated as a function wide range pH salinity conditions. effect on photodegradation rates dual observed Cl - were discussed. single binary impurity systems also examined synergetic MO oxidation reduction established at different
