糠醛渣活性炭对4,4'-硫代二苯酚和双酚F的吸附性能
Adsorption Characteristics of 4,4'-Thiodiphenol and Bisphenol F by Activated Carbon Derived from Furfural Residue
摘要
Abstract
The activated carbon derived from furfural residue using steam activation was investigated for the adsorp-tion 4,4'-thiodiphenol(TDP)and bisphenol F(BPF)from aqueous solution.Adsorption conditions including ad-sorption 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 i-sotherm 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-sec-ond-order kinetic model.Besides,the adsorption of TDP and BPF on FRAC were mainly influenced by the hydro-gen bonding,hydrophobic effect,electrostatic interaction and π-π interaction.At 298 K,the maximum adsorption capacities of FRAC for TDP and BPF were 5.408 3 mmol/g and 3.695 5 mmol/g,respectively,implying that the FRAC had a good application in endocrine disruptors wastewater treatment.关键词
