The effect of a novel electrode on the removal of Reactive Yellow 17 dye by Electrocoagulation technique

Our study considers the influence of a different electrode shape on the removal percentage of Reactive Yellow 17 (RY17) dye. The anode is a PVC tube with an iron net wrapped around the tube with a surface area of 95.88 cm(2), while the cathode is a stainless-steel tube with a surface area of 118.2 cm(2) for each cathode. Many factors were taken into account like pH, current density (CD), effect of supporting electrolytes and the effect of temperature. Under optimum conditions, the removal efficiency has reached 99.8%. The thermodynamic parameters showed the spontaneity of the mechanism of removal. The energy consumption and cost of operation were 21.7 kWh/kg dye and 1.115 US$/m(3), respectively. (C) 2022 National Institute of Oceanography and Fisheries. Hosting by Elsevier B.V.
