Abstract
Adsorption of bovine serum albumin by carbon fibres modified with titanium hydroxide by means of chemical and electrochemical deposition is investigated. The effect of fibre modification on changes in adsorption capacity with respect to the protein from the solutions of different composition is demonstrated. Adsorption of albumin was determined with the open-circuit potential and on the polarized surface of carbon fibres. Adsorption constants are calculated. It is established that titanium-containing fibre obtained as a result of the electrochemical deposition of titanium hydroxide is characterized by the maximal sorption capacity with respect to bovine serum albumin.
