Study of the adsorption of Bacillus subtilis on different fractions of activated carbons obtained from apple wood

Abstract

The paper presents the results of scientific research related to the study of adsorption processes of Bacillus subtilis bacteria on activated carbon obtained from apple wood. The activated carbons used have a specific BET area of about 2018 m2 /g and a total sorption volume of the pores equal to 1,573 cm3 /g. The peak of the adsorption is noticed after 120 minutes of contact. The sorption capacity of the activated carbon of the fraction 630- 800 μm obtained from apple wood is 2 times higher than in the case of the 800-2000 μm fraction of the same carbons for the B. subtilis bacterial species.
