Photo-polishing of palm oil mill effluent (POME) over UV/ZnO system

The photo-polishing of POME over UV /'ZnO photocatalysis system was performed in current study. The ZnO material, with band gap energy of 3.2 eV from our UV-Vis DRS measurement, was proven responsive towards 100 W UV-irradiation of 365 nm wavelength. The effect of ZnO loading was investigated B...
