摘　　要：以固废糠醛渣为原料,水蒸气活化法制备糠醛渣活性炭(FRAC),研究其对水体中4,4′-硫代二苯酚(TDP)和双酚F(BPF)的吸附性能,探讨了吸附时间、FRAC用量、pH值、温度以及TDP和BPF溶液的初始浓度对吸附过程的影响。研究结果表明:Sips和Koble-Corrigan等温模型可以很好地描述FRAC对TDP和BPF的吸附平衡数据,FRAC对TDP和BPF的吸附均是自发的放热过程。FRAC对TDP和BPF的吸附过程均符合准二级动力学模型。另外,TDP和BPF在FRAC上的吸附主要受到氢键、疏水作用、静电作用和π—π相互作用的共同影响。在298 K时,FRAC吸附TDP和BPF的最大吸附量分别为5.4083 mmol/g和3.6955 mmol/g,表明FRAC在处理内分泌干扰物废水上具有广泛的应用前景。The activated carbon derived from furfural residue using steam activation was investigated for the adsorption 4,4′-thiodiphenol(TDP)and bisphenol F(BPF)from aqueous solution.Adsorption conditions including adsorption time,FRAC dosage,pH value,temperature and initial concentration were discussed.The results showed that adsorption equilibrium data of TDP and BPF onto FRAC were well described by the Sips and Koble-Corrigan isotherm models.Thermodynamic parameters revealed that the adsorption process of TDP and BPF on FRAC was spontaneous and exothermic process.The adsorption kinetics process of TDP and BPF conformed to the pseudo-second-order kinetic model.Besides,the adsorption of TDP and BPF on FRAC were mainly influenced by the hydrogen bonding,hydrophobic effect,electrostatic interaction andπ-πinteraction.At 298 K,the maximum adsorption capacities of FRAC for TDP and BPF were 5.4083 mmol/g and 3.6955 mmol/g,respectively,implying that the FRAC had a good application in endocrine disruptors wastewater treatment.
