Abstract

Structural and adsorption properties of carbon sieves, activated carbons and graphitized carbon blacks were studied using adsorption of nitrogen, water, and high molecular organics. Several types of pore models were used to study the pore size distributions (PSD) of the adsorbents. The interfacial behavior of water adsorbed in the presence of organics depends on both the surface chemistry of an adsorbent, its structure and the characteristics of organics. A smaller size (1–10 μm) of particles of microporous Carboxen 1010 than that of Carboxen 1003 (150–200 μm) provides initially faster adsorption of lipopolysaccharide (LPS) molecules by the first carbon. However, the LPS adsorption on micro/meso/macroporous Carboxen 1003 becomes greater with time since this carbon has broad pores appropriate in size for the adsorption of large biopolymer molecules in contrast to Carboxen 1010, which adsorbs LPS mainly on the outer surface of the particles.
