摘要: 研究了H-103大孔吸附树脂对600~1000 mg/L苯酚水溶液中酚的吸附,考察了初始酚浓度、溶液pH值及温度对吸附性能的影响. 结果表明,在20 min内吸附达到平衡,吸附动力学可用拟二级动力学模型描述. 苯酚在大孔树脂上的吸附等温线很好地符合Langmuir吸附等温方程,在25℃下其饱和吸附量和Langmuir常数分别为86.00 mg/g和0.2719 L/mg.

Abstract: The removal of phenol from 600~1000 mg/L aqueous phenol solution was investigated using macroporous resins. The effects of initial concentration, pH and temperature on phenol removal were studied. The experimental results indicated that the adsorption reached equilibrium state within 20 min, and adsorption kinetics could be well described by the pseudo-second-order kinetic model. Langmuir isotherm model was better to describe the isothermal adsorption of phenol onto the macroporous resin, the saturated adsorption capacity (Qm) and Langmuir constant (KL) were 86.00 mg/g and 0.2719 L/mg, respectively. Experimental results of desorption for the resin after reaching saturation station showed that it had better desorption properties. Macroporous resin H-103 was an excellent reusing adsorption material, which can remarkably remove phenol from aqueous solution.
