| description | Abstract Novel coal gangue-based persulfate catalyst (CG-FeCl2) was successfully synthesized by the means of calcinating under nitrogen atmosphere with the addition of ferrous chloride tetrahydrate (FeCl2·4H2O). The phase transformation of the prepared materials and gas products during the heating process are thoroughly investigated. It is suggested that ferrous chloride participated in the phase transformation and formed Si-O-Fe bonds. And the main gaseous products are H2O, H2, and HCl during the heating process. Besides, the ability of CG-FeCl2 to activate peroxymonosulfate (PMS) for catalytic degradation of polycyclic aromatic hydrocarbons (PAHs) and phenol was deeply studied. More than 95% of naphthyl, phenanthrene and phenol were removed under optimizied conditions. In addition, 1O2, ·OH, and SO4 ·− were involved in the CG-FeCl2/PMS system from the free radical scavenging experiment, where 1O2 played a major role during the oxidation process. Furthermore, CG-FeCl2/PMS system exhibited superior stability in a relatively wide pH range and the presence of common anion from related degradation experiments. Overall, the novel CG-FeCl2 is an efficient and environmentally friendly catalyst, displaying potential application prospect in the field of PAHs and phenol-contaminated wastewater treatment. |
