The present paper is concerned with a research of sorption and bactericidal properties of the fine metal particles applied on the surface of active carbon fabric by chemical sedimentation method. The ascorbic acid and natrium borane were used in the study process as metals, copper and silver reducing agents. Influence of reducer and fine metal nature onto the porous structure, as well as bactericidal and sorption characteristics of obtained fibrous sorbent samples are shown. It is determined that use of ascorbic acid for synthesis of copper and silver fine particles on the active carbon fabrics surface leads to the considerable decrease in a specific surface and volumes of meso - and micropores of the obtained sorbent in comparison with initial active carbon fabric. When using the natrium borane as reducer of fine copper particles the decrease in a specific surface and volumes of sorption pores is also observed. However, when using the natrium borane, the active carbon fabric samples modified with silver particles or with their composition with fine copper particles, had the higher values of porous structure main characteristics in comparison with the initial active carbon fabric. The nature of distribution of fine metal particles at the active carbon fabric surface was investigated by the electronic microscopy method. It was found that during the chemical reduction process the particles of fine copper attached to active carbon fabric fibers, being almost evenly distributed at all surface of fabric. Particles of silver were located as crystal congestions along fibers. Sorption and bactericidal properties of the received samples of modified active carbon fabrics are investigated. Their high sensitivity to microorganism cells which remains during a long storage period is demonstrated. Herewith, the active carbon fabric, modified with particles of fine copper and silver, keeps high sorption properties.
