“…Its principle is to use the metal corrosion method to form a galvanic cell to treat wastewater. Iron-carbon micro-electrolysis is now used in many fields of wastewater treatment, including constructed wetland [ 16 , 17 ], pharmaceutical wastewater [ 18 , 19 , 20 ], petroleum wastewater, landfill leachate [ 21 ], ionic liquid wastewater [ 22 ], chemical wastewater [ 23 , 24 ], dye wastewater [ 25 , 26 ], and electroplating wastewater [ 27 , 28 , 29 ]. During the preparation of iron-carbon micro-electrolysis materials (MEMs), Fe 0 and activated carbon are first uniformly mixed in a particular proportion and then immersed in wastewater to form a large number of microscopic primary cells [ 24 , 30 ].…”

A micro-electrolysis material (MEM) was successfully prepared from carbothermal reduction of blast furnace dust (BFD) and coke as raw materials in a nitrogen atmosphere. The MEM prepared from BFD had strong ability in removing methyl orange, methylene blue, and rose bengal (the removal rates of methyl orange and methylene blue were close to 100%). X-ray diffraction showed that the iron mineral in BFD was ferric oxide, which was converted to zero-valent iron after being reduced by calcination. Scanning electron microscopy showed that nano-scale zero-valent iron particles were formed in the MEM. In short, the MEM prepared from BFD can effectively degrade organic pollutants.
