The paper presents the results of scientific research related to the study of adsorption processes of Bacillus subtilis and Bacillus cereus 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 study of the kinetics of the adsorption processes of the Bacillus subtilis and Bacillus cereus bacteria showed that the value of the maximum adsorption for the fraction 630-800 μm is established within 90 and 70 min, respectively. The maximum adsorption capacity for the B. subtilis bacteria is 0.54-0.55 McF*108/g, higher than activated charcoal obtained from apricot stones that has the values of 0.375-0.385 at 27oC. For the B.cereus bacteria the maximum adsorption was attested at the value of 0.45 McF*108/g, also higher than the adsorption capacity of the activated charcoal obtained from apricot stones, that has the value of 0.33 McF*108/g at 27oC. An example of a peak adsorption after 90 minutes of the contact for the B.subtilis bacteria is presented in the figure bellow: Fig. Adsorption isotherm of B. subtilis bacterium on AC-apple, fraction 630-800 μm at 27oC. The 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 90 to 120 minutes of contact. The adsorption values were in the range of 0.21-0.25 McF*108/g for B. subtilis and 0.26-0.28 McF*108/g for B. cereus depending on the contact time, lower than in the case of the fraction 630-800 μm. Thus, we can conclude that the sorption capacity of the activated carbon of the fraction 630-800 μm obtained from apple wood is approximately 2 times higher than in the case of the 800-2000 μm fraction of the same carbons for both bacterial species taken into study.
