  • What type of activated carbon is used in water treatment?
  • The most commonly used activated carbon in water treatment processes is a GAC made from bituminous coal with a typical surface area of 950 – 1050 m 2 g −1 and a particle size of 12 × 40 mesh (0.420 – 1.680 mm) or 8 × 30 mesh (0.590 – 2.380 mm) .
  • Can activated carbon be used in the treatment of effluents?
  • In more recent approaches, due to the properties of high surface area and disposition of active sites, activated carbon has had increasing secondary applications in the treatment of effluents as a support for catalysis (Velo-Gala et al. 2013; Iwanow et al. 2025) and electrochemical processes (Tyagi et al. 2025 ).
  • Which metal hydroxides can be used to prepare activated carbon?
  • According to a review of various articles, activation with metal hydroxides such as sodium hydroxide and potassium can be used for the preparation of activated carbon with a high surface area in the range of 3500–2300 m 2 /g (Tongpoothorn et al. 2011).
  • What are the preparation methods of activated carbon?
  • The preparation means of activated carbon are physical and chemical methods. The important advantages of chemical activation over physical activation are the process that can be accomplished even at lower temperatures and the yield obtained in chemical activation tends to be greater since burn-off char can be avoided.
