Iron removal from waters by electrocoagulation: Investigations of the various physicochemical phenomena involved

Electrocoagulation (EC) is an electrochemical technique for removal of various pollutants – in particular metal cations – from waste or groundwaters. In comparison with other metal cations, iron can be under divalent and trivalent forms, with different physicochemical properties, so various physicochemical phenomena are to occur for its removal. For the case of Fe2+ ions removal from a synthetic aqueous solution by EC with aluminium electrodes,...
