To improve biospecific properties of carbon enterosorbents for purposes of veterinary medicine methods of chemical modification of their surface were proposed. The first area is modification of carbon surfaces by the method of polycondensation of biologically active substances (arginine) and in situ formation of polymers (directly on the surface of carbon sorbents). Another method is impregnating into a porous matrix of carbon carrier nanodispersed betuline in a water soluble form. To study physicochemical characteristics of veterinary preparations synthesized the following methods were used: scanning electron microscopy (SEM) (relief and morphology); X-Ray phase analysis (phase composition); the method of low-temperature nitrogen adsorption-desorption (texture studies); X-Ray microanalysis and CHNOS Elemental Analysis (elemental composition): IR spectroscopic analysis, Kjeldahl method, H. P. Boehm's method and X-ray photoelectron spectroscopy (XPS) (surface functional composition of the synthesized samples). The article presents the study results of physicochemical properties of carbon sorbents before and after modification, which confirm the presence of polyarginine and betuline in the composition of the resulting samples.
