The advances in research on modified Activated Carbon materials in surface structure and physico-chemical properties are reviewed.The functional groups on Granular Activated Carbon materials are described as well. Some applications in the field of environmental protection such as wastewater treatment/purification and removal of SO2/NOx in furnace effluents are introduced and analyzed.
The activated carbons were obtained from industrial wastes (apricot core and grape stalk) of san juan, argentina. these were impregnated with a copper salt and thermically treated in an inert atmosphere.
So there are Coal Activated Carbon, wood, Coconut Shell Activated Carbon for water treatment, air purification, gold recovery and others. you can choose any of them if you need.
