Abstract

The initial and modified carbon sorbent modified with biologically active polymer - polyvinylpyrrolidone was obtained. Their physical and chemical properties are investigated. The influence of the process of modifying a molded carbon sorbent on its physicochemical properties is shown. The adsorption properties of molded carbon sorbents with respect to marker substances of various nature (organic dyes) under model conditions are studied. The regularities of the effect of the porous structure and the functional composition of the surface of molded carbon sorbents on the adsorption of methylene blue and methanil yellow dyes are established.The initial and modified carbon sorbent modified with biologically active polymer - polyvinylpyrrolidone was obtained. Their physical and chemical properties are investigated. The influence of the process of modifying a molded carbon sorbent on its physicochemical properties is shown. The adsorption properties of molded carbon sorbents with respect to marker substances of various nature (organic dyes) under model conditions are studied. The regularities of the effect of the porous structure and the functional composition of the surface of molded carbon sorbents on the adsorption of methylene blue and methanil yellow dyes are established.

模型条件下成型碳吸附剂对有机染料吸附性能的研究

以具有生物活性的聚合物—聚乙烯吡咯烷酮为原料，制备了初始碳吸附剂和改性碳吸附剂。研究了它们的物理和化学性质。研究了改性碳吸附剂的工艺对其物理化学性能的影响。在模拟条件下，研究了成型碳吸附剂对不同性质的标记物质(有机染料)的吸附性能。建立了成型碳吸附剂的孔隙结构和表面功能组成对亚甲基蓝和甲氧基黄染料吸附的影响规律。以具有生物活性的聚合物—聚乙烯吡咯烷酮为原料，制备了初始碳吸附剂和改性碳吸附剂。研究了它们的物理和化学性质。研究了改性碳吸附剂的工艺对其物理化学性能的影响。在模拟条件下，研究了成型碳吸附剂对不同性质的标记物质(有机染料)的吸附性能。建立了成型碳吸附剂的孔隙结构和表面功能组成对亚甲基蓝和甲氧基黄染料吸附的影响规律。
