【摘要】：以軟模板法合成介孔碳(MC),添加三聚氰胺為改性劑合成氮改性介孔碳(NMC),并進行N2吸-脫附、TEM和FT-IR表征,同時考察NMC和MC對水中壬基酚聚氧乙烯醚(NPEO10)的吸附性能。結(jié)果表明,NMC和MC的比表面積分別為579.6m~2/g和687.8m~2/g。吸附過程符合準二級動力學模型,吸附行為遵循Freundlich等溫模型,為優(yōu)惠吸附。吸附過程為可自發(fā)進行的放熱反應,無化學鍵等強鍵作用,主要以物理吸附為主。吸附飽和后的NMC和MC經(jīng)5次循環(huán)/再生后對NPEO10的去除率均在60%以上。與活性炭(AC)相比,NMC和MC的吸附效果更優(yōu)越。
[Abstract]:Soft template synthesis of mesoporous carbon (MC), adding melamine as modifier of synthetic nitrogen modified mesoporous carbon (NMC), and N2 adsorption desorption, TEM and FT-IR characterization, the combined effect of NMC and MC on the water adsorption properties of nonylphenol ethoxylates (NPEO10). The results showed that NMC and MC the specific surface area were 579.6m~2/g and 687.8m~2/g. adsorption process conformed to the pseudo two order kinetics model, the adsorption behavior followed Freundlich isotherm model for preferential adsorption. The adsorption process was an exothermic reaction can occur spontaneously, without a strong chemical bond bond interaction, mainly by physical adsorption. After adsorption of NMC and MC after 5 cycles / regeneration after the removal rate of NPEO10 was more than 60%. Compared with the activated carbon (AC), NMC and MC adsorption effect is better.
