| 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。 |

| Abstract: | 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 adsorp-tion time and the initial concentration of phenol on adsorption eficieney of phenol in aqueous solutions were dis-cussed. The results showed that after the wood cellulose was modified,the chemical adsorption existed in the ad-sorption progress for phenol in aqueous solutions,and its adsorption capacity for phenol in aqueous solutions was obviously improved. |
| Keywords: | quatermary ammoniation wood cellulose phenol adsorption |
