摘　　要：本文利用制得的改性小麦秸秆纤维素球对苯酚吸附性能进行了研究。实验结果表明:改性小麦秸秆纤维素球对苯酚的吸附30min内基本达到平衡,吸附剂对苯酚吸附量随起始质量浓度的增加而增加,且呈线性关系;在T=298K、pH=5.0时,吸附剂对苯酚的吸附量达到最大。在一定浓度、温度条件下,改性小麦秸秆纤维素球吸附苯酚的过程符合Freundlich吸附模型。吸附再生实验表明,改性小麦秸秆纤维素球对苯酚有较好的吸附再生能力。并对印染废水中的苯酚进行了实际的吸附测定。The adsorption behavior of phenol on modified wheat straw cellulose was investigated in this paper. The results showed that the adsorption equilibrium could be achieved within 30 min. The adsorption quantity was linearly increased with the increase of the initial concentration of phenol and reached the maximum at a temperature of 298 K and pH=5.0. The adsorption behavior obeyed the Freundlich isotherm adsorption model under certain concentration and temperature. Furthermore,the renewable experiments showed that the modified wheat straw cellulose had good renewable adsorption capacity for phenol.
