N2 - A novel, cost-effective, and environmentally benign process was developed to produce highly efficient carbon-based adsorbents (CBAs) from paper mill sludge. The production process required chemical activation of sludge using zinc chloride and pyrolysis at 750°C in N2 gas. The produced CBAs were characterized according to their surface area and pore size distribution using N2-BET adsorption isotherm data. Further characterization of the surface and pore structure was conducted using small angle neutron scattering (SANS). The structural features analyzed by SANS revealed the dependence of porosity on zinc chloride concentration. The presence of inaccessible pores was also determined by solvent contrast-variation SANS experiments.
