标题：p-Arsanilic acid decontamination over a wide pH range using biochar-supported manganese ferrite material as an effective persulfate catalyst: Performances and mechanisms
摘要：Highlights Satisfactory p-ASA degradation was achieved in a wide pH range. Simultaneous removal of p-ASA and the released arsenic was achieved in biochar supported MnFe2O4/persulfate system. Generation abundant reactive oxygen species via redox cycles between Mn and Fe.
