  • 摘要: 以5种化学改性剂(NH3、HCl、H2SO4、HNO3和H2O2)对活性炭进行改性,考察了化学改性对活性炭吸附磺胺甲恶唑(SMX)和布洛芬(IBP)的影响,并结合活性炭改性前后孔结构和表面化学性质的变化特征,利用Pearson相关性分析法,分析了活性炭各项理化指标与其吸附量之间的相关性。结果表明,与原炭相比,各种改性炭对SMX和IBP的吸附能力均有较大幅度提高,24 h时吸附量分别提高了36%~59%和8%~42%。活性炭的比表面积、孔容等物理性质与吸附量的相关系数绝对值均在0.4以内,表现为弱相关。对于SMX,活性炭的羧基官能团与吸附量相关系数r值在0.6~0.8之间;对于IBP,羧基、内酯基分别在吸附的前期和中后期与吸附量表现为强正相关,r达到0.6~0.8以上。本研究中活性炭的表面含氧官能团对其吸附能力表现出更为显著的影响。
    Abstract: Five modified activated carbons (ACs) were prepared by using NH3,HCl,H2SO4,HNO3 and H2O2 as modifying reagents,respectively.The adsorption behaviors of sulfamethoxazole (SMX) and ibuprofen (IBP) onto the ACs were investigated.The relationship between adsorption capacity and different physical and chemical properties of the ACs in terms of pore structure and surface functional groups was determined via Pearson correlation analysis.Results showed that the adsorption capacity increased by 36%—59% and 8%—42% for SMX and IBP,respectively,after different chemical modification treatments.The Pearson coefficient (r value) between the adsorption capacities of SMX and IBP and physical properties of the AC was found to be lower than 0.4,indicating a rather weak effect of the physical properties.For adsorption of SMX,a strong relationship between adsorption capacity and carboxyl group on the carbon surface was observed,with the r value falling in the range of 0.6—0.8.As for IBP,even stronger correlation between adsorption capacity and carboxyl group was obtained in the early stage of adsorption;while in the later stage,the adsorption capacity was shown to be positively correlated to lactone group on the ACs.Compared with physical properties,surface functional groups exhibited a more significant influence on adsorption capacity of the ACs.
