Background and purpose: Nitrate contamination in aqueous solution has become an increasingly serious environmental problem. Hence, in this study removal of nitrate in aqueous solution was reviewed using electrocoagulation (EC) and electro-fenton (EF) processes for Fe electrodes. Materials and methods: In the present study, an EC and EF reactor in a lab scale to an approximate volume of 1 liter...
