Copper-containing minerals have been extensively used in Fenton-like processes for degradation of pollutants and have exhibited great potential for environmental remediation. This work reports the first use of copper sulfide (CuS), a typical Cu-mineral, for the activation of peroxymonosulfate (PMS) for pollutant degradation; the study also elucidates the underlying mechanism of these processes. Copper sulfide effectively activated PMS to degrade di-Et phthalate (DEP). ESR, free radical quenching, XPS, X-ray diffraction analyses and DFT calculations confirmed that Ξ Cu (I)/ ΞCu (II) cycling on the surface of CuS provided the main pathway to activate PMS to produce highly oxidative species. Unlike conventional sulfate radical-based PMS activation processes, hydroxyl radical (·OH) were found to be the dominant radical in the tested CuS/PMS system, which performed more efficiently than an alternative ·OH-based oxidation system (CuS/H2O2) for DEP degradation In addition, the presence of anions such Cl- and NO-3 has limited inhibition effects on DEP degradation Overall, this study provides an efficient pathway for PMS-based environmental remediation as well as a new insight into the mechanism of PMS activation by Cu-containing minerals.
