摘 要: 以膨润土和壳聚糖为原料,制备了膨润土和壳聚糖复合吸附剂,研究了该复合吸附剂对有机废水中苯酚的吸附性能,结果表明:在温度为25℃,酸性环境(pH值为2)中,废水初始浓度为50mg/L,复合吸附剂用量为5g/L,吸附时间为1h,苯酚的去除率可达到93%以上。 A novel compound adsorbent of bentonite and chitosan was synthesized and applied to adsorb phenol in wastewater. The results show that the removal ratio of phenol is over 93% under following conditions: the wastewater is acid (pH=2) and its concentration of phenol is 50mg/L, the dosage of the adsorbent is 5g/L, the adsorption equilibrium time is lh, and the temperature is 25℃.
