Adsorption of Benzene and Water onto a Composite Sorbent Formed by an Active Carbon Layer with Grafted Cyclic Ethanolamine Macromolecules Bonded to Fabric

Isotherms of benzene and water vapor adsorption onto a composite material made of a layer of active carbon microparticles and cyclic ethanolamine macromolecules bonded to cellulose are measured. The layer is formed by carbon particles with sizes of 2.5–4 µm and grafted porous macromolecular ethanola...

Description
Summary:Isotherms of benzene and water vapor adsorption onto a composite material made of a layer of active carbon microparticles and cyclic ethanolamine macromolecules bonded to cellulose are measured. The layer is formed by carbon particles with sizes of 2.5–4 µm and grafted porous macromolecular ethanolamine. The latter combines the particles into electron-conducting and luminescent aggregates. The pores in carbon are connected with those of cyclic amines through voids formed by the cycles of oxo-amine groups and conjugated carbon groups on the surfaces of carbon particles. It is found that when the relative pressure is increased, the pores in amines, where the sorbed molecules are combined into host–guest complexes, are filled first. This is followed by estafetee filling of the pores with water or benzene molecules.
