| 摘 要： | 通过多孔炭对酚类化合物、 Cr(Ⅵ)和I2的吸附， 研究了多孔炭的表面物理化学性能对不同电性物种吸附能力的影响. 发现多孔炭对酚类化合物及Cr(Ⅵ)的吸附以化学吸附为主， 其中对酚类化合物的吸附由羧基与内酯基的表面密度合量决定， 对Cr(Ⅵ)的吸附由表面官能团中羧基和内脂基含量的合量决定； 多孔炭对I2的吸附以物理吸附为主， 由孔容决定.

| Abstract: | By adsorbing phenolic compounds, Cr(Ⅵ) and I2, the effect of the physicochemical characteristic of the porous carbon on its adsorption performance for different species was studied. It is shown that the adsorption of the porous carbon towards I2 depends on the pore volume of the porous carbon; the adsorption of the porous carbon towards phenolic compounds depends on the density of carboxylic and lactonic groups on the surface of the porous carbon; the adsorption of the porous carbon towards Cr(Ⅵ) depends on the total content of basic, carboxylic and lactonic groups on the surface of the porous carbon. |
