Electrocoagulation Removal of Sunset Yellow Dye from Aqueous Solution Using Aluminum Electrode

Abstract

Electrocoagulation (EC) is a technique in which a sacrificial electrode is used to induce the synthesis of certain coagulants. It's a straightforward and cost-effective solution. This makes it a popular method for removing contaminants from water and wastewater. The EC unit with two aluminium metal electrodes is used in this procedure. To remove the dye Sunset Yellow from aqueous solution, we set out to create a novel EC using aluminium electrodes as an anode. Direct current removal of the dye was used to verify the method's efficacy, and the effects of the applied current density were taken into account. The effects of pH, starting dye concentration, and electrolysis time were explored and adjusted for.
