Mechanical and chemical modification of wood materials - Compressed wood and oxidized charcoal
Year: 2008
Type: article
Abstract: Mechanical compression and electrolyte infusion of wood, pyrolysis, and chemical activation of the resulting charcoals produced enhanced abilities to adsorb lead ion and benzene from model polluted water solutions. Iodine number (F) and methylene blue (E) indices also showed enhancement of surface activity. Ultrasonic techniques revealed a loss of pore structure during wood compression, as water infiltration likewise indicated for the resulting charcoals, but there was not necessarily a loss of adsorption ability for the above adsorbents on subsequent charcoals. Aspen based charcoals activated by pressurized H2O2 showed the most promise among those tested.
