摘要
以3-氯-2-羟丙基三甲基氯化铵(CTA)为醚化剂,对木屑纤维素进行了改性。探讨了改性木屑纤维素用量、pH值、吸附温度、吸附时间和苯酚初始浓度等因素对静态吸附效果的影响。结果表明,木屑纤维素经改性后,对水中的苯酚的吸附过程存在化学吸附,对水中的苯酚的吸附容量得到明显提高。
Wood cellulose was modified by 3-chlorine-2-hydroxypropyl chloride(CTA) as etherizing agent.The effects of the amount of quaternary ammonium wood cellulose,pH,the adsorption temperature,the adsorption time and the initial concentration of phenol on adsorption eficiency of phenol in aqueous solutions were discussed.The results showed that after the wood cellulose was modified,the chemical adsorption existed in the adsorption progress for phenol in aqueous solutions,and its adsorption capacity for phenol in aqueous solutions was obviously improved.
