Savchyna L. Adsorption of humic substances on sorbents of different chemical structure

The theme of the thesis is to study the specifity of the sorption behavior of humus compounds (humic and fulvic acids) under extraction its from water solution by the activated carbon (AC), polymer sorbents and ionexchangers. It was shown, that the lamellar associates are formed during adsorption of the humic acids by AC. The association factor of these associates is limited by pores radius of the adsorbent and surface area per one molecule doesn't depend from value of factor association. The method of the determination was proposed for that part of the specific AC surface, which is available for the adsorption of humic and fulvic acids from water. The method of creation of a new kind of the AC ( Acant-mezo ) was carried out. Acant-mezo is characterized by developed mezoporous structure and increased adsorption capacity relatively organic matters of water humus. Key words: adsorption, humus matter, activated carbon, polymer sorbents, ionexchangers, sorbent porous structure, association factor.
