Insight on the generation of reactive oxygen species in the CaO₂/Fe(II) Fenton system and the hydroxyl radical advancing strategy.

ABSTRACT: Calcium peroxide (CaO₂) is a stable hydrogen peroxide (H₂O₂) carrier, and the CaO₂/Fe(II) system has been applied for treatment of various pollutants. It is commonly reported in the literature that hydroxyl radical (HO^●) and superoxide radical anions (O₂ ^●-) are the two main reactive oxygen species (ROSs) generated in the CaO₂/Fe(II) system. However, many of the reported results were deduced from degradation performance rather than specific testing of radical generation. Thus, the specific generation of ROSs and the influence of system conditions on ROSs yield is still unclear. To our knowledge, this is the first study specifically focusing on the generation of HO^● and O₂ ^●-</
