Charcoal Regeneration - Part 2. Modified Carbon Surface Activity and Reversibility of TNT Adsorption

Abstract

The TNT adsorption/solvent desorption cycling of activated carbon (FS300) has been studied as a function of various pretreatments. The preferential plugging of pores by the pretreatments did not enhance the regenerative property of the FS300. In conjunction with water adsorption/ desorption isotherms, the characteristics of a carbon with an improved cycling property has been elucidated. The improved property is due to a shift to larger pore volume and a larger ratio of pore opening to pore body diameters. Chemical regeneration of an activated carbon containing irreversible adsorbed TNT has been shown to be unfeasible.
