Abstract: Cellulose nanocrystal (CNC)/manganese dioxide (MnO2) hybrid material was used as raw material, and a small amount of sodium alginate (SA) was used. CNC/MnO2 porous microspheres were prepared by the air bubble template method and ion crosslinking technique. MnO2 can form a Fenton-like reaction with a small amount of hydrogen peroxide (H2O2). Taking the wastewater of the paper mill as the research object, the treatment effect of porous microspheres was detected by detecting the chroma of wastewater and Chemical oxygen demand (COD) value. The results show that after the treatment of porous microspheres and H2O2, the chroma and COD are 204 pcu and 165 mg·L-1, which meet the national sewage discharge standard and have great reusability. This study provides a green and simple strategy for the design of CNC base porous materials for wastewater treatment.
