Abstract

The development of new highly efficient sorption materials for the separation of various liquid or gaseous media is an important area of modern research that is in demand in a number of industries. The paper presents the results of studies conducted to determine the sorption capacity of a highly porous carbon material obtained by implementing two activation options - high-temperature alkaline activation and activation with additional processing of the material with steam. As a result, the obtained activated highly porous carbon material had a specific surface area of 2500-2700 m2/g and a pore volume of more than 1.3 cm3/g. A high sorption activity was established with respect to synthetic dyes - methylene blue and methylene yellow. Comparison with analogue materials showed that the resulting carbon material significantly exceeds them in sorption capacity and is a promising absorber of pollutants from aqueous solutions, which demonstrates the possibility of its use for solving environmental problems.

活性炭材料吸附特性的研究

开发用于分离各种液体或气体介质的新型高效吸附材料是现代研究的一个重要领域，在许多工业中都有需求。本文介绍了通过实施两种活化方案——高温碱性活化和用蒸汽对材料进行附加处理的活化——来确定高多孔碳材料的吸附能力的研究结果。得到的高孔活性炭材料的比表面积为2500 ~ 2700 m2/g，孔体积大于1.3 cm3/g。对合成染料亚甲基蓝和亚甲基黄均有较高的吸附活性。与模拟材料的比较表明，所得碳材料的吸附能力明显超过它们，是一种很有前途的水溶液污染物吸收剂，这表明了其用于解决环境问题的可能性。
