Highly stable heterogeneous catalysts from electric furnace dust for biodiesel production: Optimization, performance and reaction kinetics

Reed straw and electric furnace dust (EFD) waste were used to prepare magnetic Fe-C composite (EFD&C) by co-precipitation and high-temperature activation method to remove Cr(VI) from water. The magnetic EFD&C owned a large speci c surface (536.61 m 2 /g) and a porous structure (micropores and mesopores), and had an e cient removal capacity for Cr(VI). Under conditions of pH ( 2), the addition amount of EFD&C (1 g/L), the adsorption time (760 min), and the temperature (45 o C), the maximum adsorption capacity reached 111.94 mg/g. The adsorption mechanism mainly attributed to chemical adsorption (redox), Cr(VI) reduced to Cr(III) by Fe(II) and Fe(0) (from Fe 3 O 4 and Fe components in EFD) and surface functional groups of -OH, C = C, C-C and O-C = O (from biochar), and secondary attributed to physical adsorption, Cr(VI) and Cr(III) (from reduced Cr(VI)) adsorbed into the porous structure of EFD&C.This study provided guidance for the recycling of iron-containing metallurgical solid and biomass waste.
