系统研究了MOF衍生多孔碳与粉末活性炭对 2号油的吸附特性,详细考察了吸附时间、吸附剂投加量、温度及 pH等因素对其吸附性能的影响,并深入探讨了吸附机理。研究结果表明:相较于粉末活性炭,MOF衍生多孔碳表现出更优的 pH耐受性;在最佳条件下,MOF衍生多孔碳与粉末活性炭对 2号油的平衡吸附量分别为 224.95 mg/g和 194.86 mg/g。吸附动力学分析显示,二者均符合准二级动力学模型,相关系数R²>0.999。热力学研究表明,MOF衍生多孔碳对 2号油的吸附为放热过程,且以物理吸附为主。
The adsorption characteristics of MOF⁃derived porous carbon and powdered activated carbon for No.2 oilwere systematically investigated. The effects of adsorption time, adsorbent dosage, temperature, and pH on their adsorptionperformance were examined in detail, and the adsorption mechanisms were thoroughly discussed. Results demonstratethat MOF⁃derived porous carbon exhibits superior pH tolerance compared to powdered activated carbon. Under optimalconditions, the equilibrium adsorption capacities of MOF⁃derived porous carbon and powdered activated carbon forNo.2 oil reach 224.95 mg/g and 194.86 mg/g, respectively. Adsorption kinetic analysis reveals that both follow the pseudo⁃second⁃order kinetic model with correlation coefficients R2 > 0.999. Thermodynamic studies indicate that the adsorptionof No.2 oil by MOF⁃derived porous carbon is an exothermic process dominated by physical adsorption.
