文章探讨了几种不同起源活性炭对海洋溢油的吸附能力。结果表明,活性炭对溢油的吸附能力不仅与其比表面积和孔体积有关,还受到其孔尺寸的影响。其中,煤基活性炭(商业活性炭)和玉米秸秆基活性炭虽具有较高的比表面积和孔体积,但是由于其结构骨架以微孔为主,难以吸附长链烷烃、大尺寸环烷烃及芳烃等溢油的主要组成分子,因此其吸附能力(5.6g/g)远低于比表面积及孔体积并不显著的,但具有介孔结构和大孔结构的硅藻土基活性炭(32.7g/g)。
The article discusses the adsorption capacity of several different origins of activated carbon on marine oil spills. The results show that the adsorption capacity of activated carbon to oil spill is not only related to its specific surface area and pore volume, but also influenced by its pore size. Among them, coal-based activated carbon (commercial activated carbon) and corn stalk-based activated carbon have high specific surface area and pore volume, but due to the porous structure of their skeleton, it is difficult to adsorb long-chain alkanes, large-sized naphthenes and aromatic hydrocarbons (5.6g / g) is far lower than the specific surface area and pore volume. However, the diatomite-based activated carbon (32.7g / g) with mesoporous structure and macroporous structure has the highest adsorption capacity .
