  • Which adsorbent is used to treat wastewater?
  • Activated carbon is the most preferred adsorbent to treat wastewater but its use is limited because of high cost. Therefore, several low-cost and natural materials and wastes have been used as precursors for the preparation of alternative adsorbents.
  • Which waste is used as a low-cost adsorbent for water treatment?
  • Some industrial wastes/by-products that have been applied as low-cost adsorbents for water treatment are waste slurry, areca waste, and liquor waste from the paper industry (Aljerf 2016; A; Tripathi & Rawat Ranjan 2015). Fly ash is another waste/by-product composed of SiO 2, Al 2 O 3, and Fe 2 O 3 of coal firing by a thermal coal plant.
  • Do low-cost adsorbents remove pollutants?
  • This updated review provides information on the different applications of low-cost adsorbents in removing pollutants and their adsorption capacities in an attempt to deploy the recent sustainable low-cost adsorbents with high removal efficiencies for water treatment.
  • Are industrial adsorbents suitable for drinking water treatment?
  • Generally, industrial by-products have exhibited low adsorption efficiencies which makes them less preferable to consider for drinking water treatment in comparison to the other low-cost adsorbents.
