Electrochemical Properties and Biological Activity of Carbon Materials Modified by Polypyrrole

Prospects of development of an electrochemically controlled hemosorption detoxification method are very promising because this method combines biocompatibility of activated carbon with high adsorptivity towards toxic compounds. The present work is an attempt to develop controlled detoxification processes on carbon adsorbents modified by electroconductive polypyrrole. Electropolymerization of pyrrole on activated carbon AG-3 had added biocompatibility to a material that is aggressive towards blood. The magnitude and direction of open circuit potential (OCP) shifts for the carbon materials studied depend on the conditions of electropolymerization. Adsorptivity of AG-3 covered by polypyrrole was increased compared with untreated carbon.
