A novel process, KMnO4-Fe2+ process, was developed in this study for As(III) removal. In this process, As(III) was removed by permanganate oxidation and subsequent coagulation with the Fe(III) formed in-situ, which was generated by oxidizing Fe(II) with permanganate. As(III) removal in KMnO4-Fe2+ process decreased with increasing pH at various permanganate dosages and ferrous dosages. Zeta potential...
