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, Fe۳O۴, and other ingredients go into the making of the hydrogel. Following are some factors that changed photo-Fenton activity: (pH, H۲O۲ 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 ۶۰ minutes of UV exposure, The MB dye degradation in the Cr۶+/Fe۳O۴/CS hydrogel composite was ۹۰.۴%.
