Removal of cadmium ions via the magnetic biochar synthesised from sugarcane bagasse: Factors affecting yield and adsorption capability.

The sugarcane bagasse (SCB) was a precursor in synthesising magnetic biochar using a modified single-stage electric muffle furnace to remove Cd2+ ions in industrial wastewater. Nickel (II) oxide (NiO2) was added to boost the efficiency of yield and the removal of heavy metals. The magnetic biochar (...
