[Increase in the effectiveness of microbial absorption on activated charcoal upon sorbent polarization].

The effect of Staphylococcus albus and the contact time on hydrolytic adsorption of ions on activated charcoal SKN-2K in the physiological solution (0.9% NaCl) was investigated. Experiments were performed without polarization or with cathodic and anodic polarization of the adsorbent. The adsorbed microorganisms decreased the rate of electrolyte ion adsorption, especially in case of cathodic polarization. When activate charcoal was at negative potential (-0.2 V), up to 95% of active microorganisms was adsorbed at the initial concentration of 5.75.10(6) microorganisms per ml, while in case of anodic polarization only 43-44% of microorganisms was adsorbed.
