We determined the efficiency of extraction of the Cu2+ ions by a dry magnetically-controlled biosorbent based on Sacharomyces CEREVISIAE yeast, obtained by magnetohydrodynamic stirring in the crossed electric and magnetic fields. The influence of different concentrations of magnetic nanoparticles and yeast cells on the magnetic favorability was also revealed. The optimum content of magnetite is 0.2–0.6 %, biosorbent possesses maximum magnetic favorability and better stability. Sorption capacity of dry MCBS, manufactured by the MHDS method in the crossed electric and magnetic fields, in relation to the ions of copper, is 82 %, and for the MCBS manufactured at mechanical agitation is 60 %. Larger sorption capacity is observed for dry magnetically-controlled biosorbent, obtained using magnetohydrodynamic stirring in the crossed electric and magnetic fields at magnetite concentration 0.2–0.6 %.Magnetic favorability of dry MCBS, manufactured by the MHDS method in the crossed electric and magnetic fields, is 60 % higher. Magnetically-controlled biosorbent, manufactured by the MHDS method in the crossed electric and magnetic fields, retains its magnetic favorability in the process of stirring within 2–4 %, while that manufactured at mechanical agitation – within 28–34 %.The process of active and passive biosorption demonstrates that a part of the magnetite nanoparticles was attached to the surface of biosorbent. This indicates that the passive and active sorption proceeds during the process of interaction between yeast cells and magnetite nanoparticles.Studies of structure and properties of dry MCBS obtained by different methods of stirring will help select biosorbent with the best properties. And it is certainly the MCBS manufactured by the MHDS method in the crossed electric and magnetic fields. It has a number of advantages, which are described above, in comparison with the MCBS, manufactured with mechanical agitation. In future it is recommended to use dry MCBS manufactured by the MHDS method in the crossed ...
