Y1 - 2016. N2 - Coal, just like other fossil fuels such as oil and natural gas, is mainly used as a non-renewable source of energy.
The recent research interest in low-cost alternatives to activated carbon for waste and wastewater treatment is reviewed. An examination of the selection criteria and activation methods for the preparation of active carbon is followed by a critical assessment of low-cost adsorbents prepared from carbonaceous industrial wastes, agricultural by-products and mineral-derived sources.
