Influence of surface chemistry on adsorption and decomposition of aqueous pollutants.

虽然活性碳(AC)已被广泛用于工业规模的水相污染物去除，但AC的表面化学与其吸附能力之间的关系还不是很清楚。本文考察了表面性质对吸附去除水中有机和无机污染物的影响，在石墨片边缘引入氧和氮原子，即使在酸性溶液中也能有效地去除污染水中的重金属。

Though activated carbons (ACs) have been widely employed to remove pollutants in aqueous phase in industrial scale, the relationship between surface chemistry of AC and adsorption ability onto AC is not well understood. In the present study, influence of surface nature on the adsorptive removal of organic and inorganic pollutants in water was examined and introducing oxygen and nitrogen atoms at the edge of grapheme sheets resulted in an effective surface for the heavy metal removal from contaminated water even in the acidic solutions.
