  • 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) .
  • How to develop surface modified activated carbon?
  • Various methods such as, acid treatment, base treatment, impregnation treatment, ozone treatment, surfactant treatment, plasma treatment and microwave treatment have been studied to develop surface modified activated carbons.
  • Does oxygen plasma treatment increase surface area of activated carbon fibers?
  • The oxygen plasma treatment of activated carbon fibers (ACFs) was carried out to introduce oxygen-containing groups onto carbon surfaces . It was found that the oxygen functional groups, such as C 6 H 5 OH and O⋯C O, were increased after the plasma treatment. However, a slight decrease of specific surface area was also noticed.
