A Comparison Study between Wood Flour and Its Derived Biochar for the Enhancement of the Peroxydisulfate Activation Capability of Fe3O4

In this study, both wood flour (WF) and flour-derived biochar (WFB) were used as supports for Fe3O4 to activate peroxydisulfate (PDS). The role of different carriers was investigated emphatically from the aspects catalyst properties, degradation kinetics bisphenol A (BPA), effects important parameters, generation reactive oxygen species (ROS). Results showed that WF WFB could serve good support Fe3O4, which control release iron into solution increase specific surface areas (SSAs). WFB/Fe3O4 had stronger PDS activation capability than WF/Fe3O4 mainly due larger SSA ability WFB. Both radical (•OH SO4•−) non-radical pathways, including 1O2 high-valent iron-oxo species, contributed BPA in WFB/Fe3O4–PDS process. Moreover, also release, better reusability, higher mineralization efficiency WF/Fe3O4.
