Abstract

      Organic contaminants are used to be found in industrial wastewater treatment procedures, and heavy metal ion removal is difficult. Photo Fenton reaction activity was exploited in this study to decompose organic contaminants using a functional composite hydrogel. Polyacrylonitrile (PAN), Fe3O4 particles, and graphene oxide make up the hydrogel (GO). It is made from GO/ Fe3O4 and is made using the precipitation technique. GO is made from graphite using the Hummers process. And it has exceptional mechanical strength and Photo-Fenton activity as a result of various breakdown data that were influenced differently, such as H2O2 concentration, dye concentration, temperature, and irradiation duration. Atomic Force Microscopy (AFM) was used to examine the composite's shape and average diameter. Under UV irradiation, the degradation of Methylene Blue dye (M.B) by the PAN/Fe3O4/GO hydrogel composite reached 100% after 90 min. Meanwhile, after 90 min of visible irradiation, COD (Chemical Oxygen Demand) dropped to 9 mg/L and dropped to low (sub range) after two anda half hours. This research proposes a new method for processing high-consistency industrial effluent that is difficult to decompose.
