Abstract

This paper describes the adsorptive, structural, and textural characteristics of carbon sorbents of various origins: OU-A activated charcoal powder (unmodified and modified with a cellulose polyelectrolyte), AUT-MI fibrous activated carbon, and expanded graphite intercalated with sulfuric acid. In accordance with their pore structure parameters and specific surface area, the highest adsorption capacity for water-soluble markers (iodine and methylene blue) and anionic surfactants is offered by the activated charcoal and fibrous carbon. Surface modification with an anionic polymer increases the adsorption of positively charged methylene blue molecules.
