表面憎水性活性炭的制造和表征

Preparation and Characterization of a Surface Hydrophobic Activated Carbon

活性炭是一种应用广泛的吸附催化剂,具有发达的空隙结构和巨大的比表面积,在环境污染处理,尤其是去除废水中有机污染物等方面,具有广泛的应用。但是,通常在活性炭的活化过程中,活性炭表面产生一些亲水性的基团,使其吸附废水中有机污染物量减少。文章通过活性炭表面改性,赋予活性炭表面一个合适的憎水性,从而增强其在废水中吸附有机污染物的能力。

Activated carbon as a widely used catalyst and adsorption material with a developed interspaces structure and a huge surface area is applied to environment pollution control especially to remove organic matters in wastewater. However there were many hydrophilic groups produced by activation on the surface of activated carbon which will be imparted with an appropriate degree of hydrophobicity. Activated carbon was modified to get a hydrophobic surface for the purpose of increasing the adsorption capacity of organic matters.
