Removal of Acidic Dye by Electrochemical Method Using Polymeric Nanofiber Containing Reduced Graphene Oxide Nanoparticles and Catalyst

In this study, to remove the acidic blue 92 during the heterogeneous electro-fenton process, the electrospinning method produced a nanofiber layer and used it as the cathode. Polyaniline/nylon66 nanofiber (PANI/PA66) was produced by the electrospinning method to produce such a nanofibrous electrode. Reduced graphene oxide nanoparticles were added to the polymeric solution to improve the conductivity of the nanofibrous electrode and the dye removal percentage. Magnetic iron nanoparticles were also used as fenton catalysts (PANI/PA66/rGO/Fe3O4). The optimal electrospinning conditions were determined by response surface methodology. Electro fenton process for dye removal was carried out in a two-electrode system using PANI/PA 66 / rGO 6 % / Fe3O4 as a cathode in 120 minutes, and the highest dye removal percentage achieved was 91.78 %. Also, the effect of selecting essential parameters on the dye removal efficiency, such as pH, initial dye concentration, and Fe3O4 dosage, was investigated.
