Study of the Adsorption of Bacillus subtilis and Bacillus cereus Bacteria on Enterosorbent Obtained from Apricot Kernels

This paper presents the results of scientific research on structural parameters and adsorption capacity activated carbon obtained from apricot kernels (AC-A) in a fluidized layer. The highlight fact that described procedure allows obtaining mesoporous adsorbent with increased capacities (SBET = 1424 m2/g) quality indices corresponding to requirements enterosorbents imposed by European Pharmacopoeia Monograph. Adsorption kinetics studies bacteria Bacillus subtilis cereus have shown time establish equilibrium is 75–90 min. mentioned enterosorbent AC-A was studied depending temperature (26 36 °C) pH solution (1.97–4.05). Scanning Electron Microscopy (SEM) showed immobilization takes place outer surface due geometric dimensions are often larger than macro diameter pores. FTIR investigations also indicated presence carbon.
