The paper presents the results of scientific research related to the study of adsorption processes of Bacillus cereusbacteria 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 study of the kinetics of the adsorption processes of the Bacillus cereusbacteria showed that the value of the maximum adsorption for the fraction 630-800 μm is established within 120 min. The maximum adsorption capacity is 0,6 McF*108/g, higher than activated charcoal obtained from apricot stones that has the values of 0,375-0,385 at 27oC. The peak of the adsorption is presented in the figure bellow:tableThe kinetics of the adsorption processes of activated carbon obtained from
apple wood (fraction 800-2000 μm) for the same bacteria were evaluated at 27oC.
The main sorptive properties were attested after 60 to 120 minutes of contact.
The adsorption values are in the range of 1,1-1,2 McF*108/g depending on the
contact time, higher than in the case of the fraction 630-800 μm and also higher
than in the case of activated carbons obtained from apricot stones tested at 27oC
and 37oC. The peak of the adsorption is noticed after 120 minutes of contact. We
can conclude that the sorption capacity of the activated carbon of the fraction
800-2000 μm obtained from apple wood is approximately 2 times higher than in
the case of the 630-800 μm fraction of the same carbons for the B. cereus bacterial
species.
