Abstract

Abstract. Thanks to their vast surface area, activated carbons are materials of great interest. They are used as adsorbents for both liquid- and gaseous impurities. To improve their properties, impregnation with different substances is conducted. In this paper, such an impregnation was done using copper(II), manganese(II), silver(I), and zinc(II) salts. The aim was to compare the inner structure of the impregnated activated carbon with a non-impregnated one. It was done by Brunauer-Emmett-Teller (BET) adsorption-desorption isotherms that were plotted and described. Lastly, the pore size and volume were determined by Barrett-Joyner-Halenda (BJH) method. The results show that the presence of zinc(II) salts helped to develop the mesoporous structure of activated carbon and resulted in an increase in the surface area of the sorbents, while silver(I) decreased it.
特定过渡金属离子浸渍活性炭对其吸附性能和孔径的影响
摘要由于其巨大的表面积,活性炭是人们非常感兴趣的材料。它们被用作液体和气体杂质的吸附剂。为了改善其性能,对其进行了不同物质的浸渍。本文采用铜(II)、锰(II)、银(I)和锌(II)盐进行浸渍。目的是比较浸渍活性炭与未浸渍活性炭的内部结构。用brunauer - emmet - teller (BET)吸附-解吸等温线进行了表征。最后,采用Barrett-Joyner-Halenda (BJH)法测定孔隙大小和体积。结果表明,锌(II)盐的存在有助于活性炭形成介孔结构,使吸附剂的表面积增大,而银(I)盐的存在使吸附剂的表面积减小。
