Abstract

Porous carbons with surface area of 898 and 1461m²g^-1 were prepared from refuse-derived fuel (RDF-5) waste via NaOH activation at 780°C and a NaOH/char weight ratio of 1 (RDFN1) and 2 (RDFN2), respectively. Changes in surface morphology and chemical compositions of the carbons were studied by SEM and elemental analysis. The ability of these carbons for the adsorption of 4-chlorophenol (4-CP), acid blue 74 (AB74), and methylene blue (MB) from aqueous solution were examined. Various isotherm (Frenudlich, Langmuir, and Sips) and kinetic (pseudo-first-order, pseudo-second-order, and Elovich) equations were fitted by nonlinear regression using SigmaPlot 11 software. It was shown that the pseudo-second-order equation best described adsorption of 4-CP and AB74 on RDFN2, whereas Elovich equation best followed adsorption of three solutes on RDFN1. The similarity index between the Sips and Langmuir or Freundlich equations was finally proposed from isotherm parameters obtained based on 59 adsorption systems.
