Abstract

Abstract The aim of this study is to investigate the efficiency of heterogeneous Photo-bio-Fenton-like process and adsorption process for phosphorus removal from wastewater. The results showed that both of these processes can reach 98 and 92% removal efficiencies phosphate (P) and Chemical Oxygen Demand (COD), respectively. The findings of kinetic and isotherm studies revealed that data of P removal highly correlated with the pseudo-second-order kinetic model and Langmuir isotherm. The quenching experiments determined that both hydroxyl radicals and sulfate radicals are key factors for the removal of contamination and the sulfate radicals were also the dominant radicals.
