A laboratory experiment illustrating the principle and application of electrocoagulation is described using oil-water emulsions as the medium to be treated and iron as the anode. The destabilized oil droplets are shown to be separated from the aqueous phase via electrolysis and iron hydrooxide coagulant formation. This simple experiment is shown to afford opportunities for exploring concepts related to colloid chemistry, electrochemistry, corrosion, and analytical chemistry.
