The electrowinning cell utilised a 35 cm 2 contact surface area mesh titanium anode and stainless-steel plate cathode spaced 13 cm apart. The cathode was connected to the negative pole of a DC power supply, while the anode was connected to the positive pole. The DC power supply had a maximum voltage >24 V, was capable of operating under constant current or voltage mode and had the capability to be power factor corrected. To control agitation speed, each tank of the electrochemical cell used in this project was equipped with an overhead stirrer. The WPCB iodide leachate and iodide electrolyte solution used in the laboratory experiment was prepared in a low-form glass beaker on a heating plate, equipped with a 3D printed system closure, an overhead mechanical agitator, and a thermometer. Figure shows the leaching set-up.
