摘要

在本研究中,碳化稻壳(CRH)被用作获得碳单质实验样品的原料。选择碳化稻壳的原因在于其环保性和可用性,以及最佳的物理化学和结构特征。在 900-950 °C 的蒸汽中对稻壳进行碳化,然后用 2-15 % 的硝酸进行脱盐处理,即可获得 CRH。这篇文章专门研究了用于医药的碳材料。在这项工作中,获得了 9 个具有不同成分比例的碳单质样品。这些样品是在 CRH 和塑料块(用作粘合剂)的基础上获得的。确定了具有最佳特性的样品:吸附能力 75.6%,根据多流 BET 法测定的比表面 360.56 m2,生物介质中乙醇的吸附率 50%。吸附能力是用亚甲蓝染料测定的,亚甲蓝染料模拟中等分子量的有毒物质。比表面积在吸附仪上用多精度 BET 法测定,乙醇在生物介质中的吸附量在色谱仪上测定。结果表明,与纯碳成分相比,碳硅成分的吸附剂具有最温和的吸附性。8 号样品具有较高的比表面积和吸附能力,可吸附各种来源的毒素,包括生物液

Experimental research on optimizing carbon materials for filtration applications in medicine

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
