Study of Enterosorption Activity of Carbon Sorbents Based on Organosolvent Lignin of Fir Wood

Abstract

The sorption activity of carbon sorbents obtained from organosolvent lignin of fir wood with respect to methylene blue, vitamin B 12 and gelatin was studied. The influence of pH values of model solutions on the sorption of methylene blue and vitamin B 12 was established. The data on the kinetics of sorption of these marker substances by carbon sorbents from lignin of fir woodwas presented. It was found that the ability of the studied sorbents to sorb the marker substancesexceeds the industrial activated carbons usedfor medical purposes.
