"Carbon prepared from the wood of Ailanthus altissima, at 400 and 800 degrees C was used to adsorb acid blue 1 from aqueous solution at 10 degrees C and 45 degrees C. Characterization by XRD, SEM, EDS and FTIR shows that the surfaces contain functional groups like carboxyl which disappear at 800 degrees C and thus favor the exposure of more porous structural surfaces which enhance the adsorption capacity. Relatively high amounts of carbon with respect to oxygen were found with the increase in activation temperature," scientists in Peshawar, Pakistan report.
"First order, Bangham and parabolic models were found to fit the adsorption kinetic data. The reaction rate ...
