利用环糊精处理含酚废水的研究

文章利用β-环糊精(β-CD)的结构和性能对含苯酚废水进行处理,通过实验考查了吸附时间、pH、温度、用量、废液浓度等因素对吸附率的影响,得出实验的最佳工艺条件为:吸附时间为240 min,pH为5~7,β-CD用量为4 g/L,苯酚初始浓度为100 mg/L,吸附温度40℃,最高吸附率可以达到42.5%。进一步研究在30℃条件下,β-CD吸附苯酚废水过程符合Freundlieh吸附模型。

Study on Treatment of Wastewater Containing Phenol with Cyclodextrin

In the paper, by using β - cyclodextrin （ β -CD） on the structures and properties of phenol containing wastewater treatment, Through experiments, the influence of adsorption time, pH, temperature, dosage, wastewater concentration on adsorption rate. The highest adsorption efficiency could be up to 42.5 % by β-cyclodextfin when the adsorption experiment was run at 40 ℃for 240 min with pH value 6.0 and β-cyclodextrin 4 g/L. The adsorption thermodynamics curves of cyclodextrin were fit with the Freundlieh adsorption isotherm model at 30 ℃
