We investigated the effect of co-existing anions of Cl−, SO42−, NO3−, CO32−, and HCO3− on potassium persulfate (PS) activation by multiwalled carbon nanotubes (MWCNTs) and N-doped MWCNTs (MWCNTs) for acetaminophen (ACP) degradation.

In-situ chemical oxidation (ISCO) based on peroxide activation is one of the most promising technologies for removing organic contaminants from natural groundwater (NGW). However, use of the most common form of hydrogen peroxide (H
