Role of co-existing anions in non-radical and radical processes of carbocatalyzed persulfate activation for acetaminophen degradation

We investigated the effect of co-existing anions of Cl − , SO 4 2− , NO 3 − , CO 3 2− , and HCO 3 − on potassium persulfate (PS) activation by multiwalled carbon nanotubes (MWCNTs) and N-doped MWCNTs (MWCNTs) for acetaminophen (ACP) degradation.
