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 |

The peak of the adsorption is presented in the figure bellow:</p><p>table</p><p>The kinetics of the adsorption processes of activated carbon obtained from<br />apple wood (fraction 800-2000 μm) for the same bacteria were evaluated at 27oC.<br />The main sorptive properties were attested after 60 to 120 minutes of contact.<br />The adsorption values are in the range of 1,1-1,2 McF*108/g depending on the<br />contact time, higher than in the case of the fraction 630-800 μm and also higher<br />than in the case of activated carbons obtained from apricot stones tested at 27oC<br />and 37oC. The peak of the adsorption is noticed after 120 minutes of contact. We<br />can conclude that the sorption capacity of the activated carbon of the fraction<br />800-2000 μm obtained from apple wood is approximately 2 times higher than in<br />the case of the 630-800 μm fraction of the same carbons for the B. cereus bacterial<br />species.</p></description> </descriptions> <formats> <format>application/pdf</format> </formats> </resource>
