The synthetic aqueous solution containing phosphate was treated using electrochemical oxidation of ferrous iron to produce the fresh precipitation of iron hydroxide or iron (oxyhydr)oxide. The results show that phosphate removal efficiency (PRE) for FPV (aqueous solution containing Fe2+ and phosphate, and voltage is supplied) is the highest and is 90% in 50 min. Meantime, PRE has a high correlation with iron relative consumption. Additionally, the removal mechanism on phosphate is speculated by Fourier transformed infrared analysis on the settl...
