Theoretical aspects of adsorption of polar substances from polar solvents

The efficiency of adsorbents for hemoperfusion and dialysate regeneration can be increased if suitable catalysts are fixed on their surface in an appropriate density. Suitable catalysts are oxides and salts of the transition metals. The appropriate surface density of the catalysts depends on the molecular data of both catalyst and toxin to be removed, as well as on the distribution of the adsorption sites on the adsorbent surface area. The distribution of the adsorption sites is determined by means of photoelectron spectroscopy and adsorption and desorption measurements.
