  • Can coal be used as a adsorbent?
  • This review explores the use of coal, not as an energy source used for generating electricity, but as a low cost adsorbent in water and wastewater treatment processes. In fact, today, coal-based adsorbents still attract considerable interest in their usage.
  • Are coal-based adsorbents effective in water and wastewater treatment?
  • This is because besides being inexpensive and abundant in many countries, coal possesses very exciting characteristics that make it aneffective adsorbent for the removal of various organic and inorganic pollutants. In this regard, this review paper critically analyses the use of coal-based adsorbents in the treatment of water and wastewater.
  • Can coal be used in water and wastewater treatment?
  • Therefore, in conclusion, the use of coal in water and wastewater treatment, now and in future,depends upon the continuation of research into the development of cost-effective coal-based adsorbents. Simply stated, further research work on developing cost-effective coal-based adsorbents is highly recommended.
  • Which adsorbent corroborates well with increasing carbon content compared to bituminous coal?
  • Furthermore, the increasing sorption capacity (e.g., in lignite coal compared to bituminous coal) also corroborates well with decreasing carbon content and increasing ash content of the coal-based adsorbents , .
