Carbon materials: theory and practice.

Abstract

The goal of this chapter is to show results of systematic calculations for adsorption from binary non-electrolyte solutions using Lattice Density Functional Theory (LDFT). It is shown that several of the basic types of adsorption isotherms in the experimental classification Correspondence/Reprint request: Dr. hab. Artur P. Terzyk, Prof. of N.C.U., Dept.

Gauden et al. 518 proposed by Giles et al. can be predicted from LDFT with reasonable estimates for the adsorbent-adsorbate and adsorbate-adsorbate interaction energies. Varying the values of the energetic parameters allows one to investigate the behaviour of adsorption isotherms for solutions, the phase transitions that can occur, and the changes from one classification to another. LDFT predictions are compared with experimental results published by several authors. Moreover we show the fitting of LDFT model to experimental data of sorption on activated carbons.
