In the present investigation, carbonized rice husk (CRH) were used as a feedstock for obtaining experimental samples of a carbon monolith. The choice of carbonized rice husk is due to environmental friendliness and availability, optimal physico-chemical and structural features. CRH was obtained by carbonization of rice husks in steam at 900–950 °C, followed by demineralization of 2–15 % nitric acid. The article is devoted to the study of carbon material for use in medicine. In this work, 9 samples of a carbon monolith with different ratios of components were obtained. The samples were obtained on the basis of CRH and plastic mass, which were used as binders. A sample with optimal characteristics was determined: sorption capacity 75.6 %, specific surface according to the multi-current BET method 360.56 m2, sorption of ethyl alcohol in biological media 50 %. Sorption capacity was determined using methylene blue dye, which simulates medium molecular weight toxicants. The specific surface area was measured on a sorbtometer using the multiprecision BET method, and the sorption of ethyl alcohol in biological media was determined on a chromatograph. It has been established that the carbon-silicon composition of the sorbent has the mildest sorption compared to the pure carbon composition. Sample No. 8 has a high specific surface area and sorption capacity, which will allow it to absorb a wide range of toxins of various origins, including biological fluids
