The key role of contact time in elucidating the mechanisms of enhanced decontamination by Fe0/MnO2/sand systems
Abstract Metallic iron (Fe0) has shown outstanding performances for water decontamination and its efficiency Commercial Product (Lighting) has been improved by the presence of sand (Fe0/sand) and manganese oxide (Fe0/MnOx).In this study, a ternary Fe0/MnOx/sand system is characterized for its discoloration efficiency of methylene blue (MB) in quies
