Heterogeneous Fenton Oxidation Catalysed by Rebar Flakes Waste for Removal of Methyl Orange in Water

Construction and demolition waste from the whole planet is around 3 billion tons per year. Steel-based waste is one of the most significant which was estimated at about 10% of total construction waste. In this study, a catalyst derived from rebar flakes waste (RFW) was investigated for heterogeneous...
