文摘

LaMO3 (M: Co, Cu, Fe, and Ni) are studied for activating peroxymonosulfate (POMS). RB decolorization is used as a model test to evaluate POMS activation by LaMO3. Kinetics and activation energies of RB decolorization by LaMO3 are determined. LaCoO3 is the most effective LaMO3 to activate POMS for degrading RB dye. Mechanisms of RB decolorization and activation of POMS by LaCoO3 are revealed.
