摘要 研究了β-环糊精(β-CD)经交联剂(TDI)制备的新型交联β-环糊精(TDI-β-CD)用于苯酚废水的处理。通过实验得到了较佳的废水处理和再生工艺为:苯酚废水的pH值控制在5～7,TDI-β-CD添加浓度不超过40 mg/mL;苯酚废水初始浓度越高吸附率越低;TDI-β-CD多次使用后可用甲醇浸泡、洗涤进行再生,再生10次吸附率仍然在88%以上。 The cross-kinked β-cyclodextrin with cross-linking agent was used in the treatment of wastewate containing phenol.Technological parameters were optimized by adsorption experiments.Regeneration times and adsorptive capacity were investigated.Controlling limit pH of phenol wastewate was 5-7.The maximum amount of polymers was 40 mg/mL.The adsorption ratio and adsorbability were lower with the increasing of initial concentration of phenol wastewate.Regeneration process of adsorbent soaked by methyl alcohol and washed by deionized water.The adsorption efficiency retained more than 88% after 10 times regeneration.
