【摘要】 综述了国内外学者对氧化改性和还原改性活性炭吸附有机物的研究进展。氧化改性和还原改性活性炭的比表面积、表面官能团和表面pHpzc都发生了变化,因此对液态和气态有机物的吸附发生变化。吸附机理主要是通过改变三种力的作用形式和大小,即扩散力、供-受电子机制和静电作用。氧化改性活性炭不利于吸附水溶液中的有机物,还原改性活性炭有利于吸附水溶液中的有机物,氧化改性和还原改性活性炭都有利于吸附气态中极性有机物。更多还原

【Abstract】 In this article, progress in oxidized and reduced activated carbon for adsorption of organic substance was discussed. The specific surface area, surface functional groups and surface pHpzc are changed, influencing the adsorption of organic substance in liquid and gas. The theory of adsorption are dispersion forces, electron donor-acceptor interaction and electrostatic reaction, which are also changed by chemical modification. Oxidation is not beneficial for adsorption of organic substances in water, but reduction is opposite. Both of them are beneficial for adsorption of polar organic substances in gas.更多还原
