摘要：

Removing heavy metal ions from organic contaminants by industrial wastewater treatment systems is a difficult challenge. In this study, organic contaminants were degraded using functional composite hydrogels with photo-Fenton reaction activity. Chromium, chitosan, Fe3O4, and other ingredients go into the making of the hydrogel. Following are some factors that changed photo-Fenton activity: (pH, H2O2 conc., temp, and exposure period). AFM was used to analyze the composite's morphology and typical diameter (AFM). It investigated how much chromium adsorbs on chitosan (BET). After 60 minutes of UV exposure, The MB dye degradation in the Cr6+/Fe3O4/CS hydrogel composite was 90.4%.
