Using iron filings, activated carbon power and clay as raw materials, the granular iron-carbon micro-electrolysis packing was made by the method of calcination.
As one of the important chemical raw materials and organic intermediates, CBs are primary materials in dyes, pharmaceuticals, pesticides and many other organic chemical industries [1].
The packing was prepared using the following procedures: (1) All the materials (iron filings, activated carbon powder and clay) were mixed fully at the mass ratio of 60: 10: (20-23). (2) A small amount of water was added to the materials.
