Impact of characteristic of activated carbons on the efficiency of removal from water of pharmaceutical preparations of various chemical nature

Abstract

The article has investigated regularities of adsorption of sulfanilamide, sulfathiazole, levamizole and procaine on activated carbons KAU and Filtrasorb F400. Within the interval of concentrations 0.1–1 mol/dm³ the series of adsorption affinity of substances under research on both carbons coincide. Adsorption values decrease in the following sequence: sulfanilamide > sulfathiazole > procaine > levamizole. It has been shown that for the removal from water of the mixture of pharmaceutical preparations with different physicochemical properties it is expedient that the combination of mainly microporous carbon sorbents have different surface chemistry.
