采用环氧氯丙烷和三乙胺对分离出来的亚麻屑纤维素进行改性，制备了一种新型吸附剂。采用扫 描电子显微镜和傅里叶变换红外光谱仪分别观察了所制备的吸附剂的表面形貌并分析了主要官能团，研究了其对活性翠蓝染料的吸附性能，探讨了吸附时间、吸附剂用量、染料初始浓度及pH等对吸附的影响。结果表明，随时间延长吸附容量逐渐增加，180 min 后吸附即可达到平衡，升高温度有利于吸附反应的进行，40 ℃时最大吸附容量为198.45 mg/g；染料初始浓度较高时，吸附容量较大，吸附受pH的影响较为明显。

Cellulose from flax shive was separated and modified with epoxychloropropane and triethylamine，and utilized as an adsorbent for the removal of reactive turquoise blue (RTB) from aqueous solutions. The surface morphology and functional groups of the adsorbent were analyzed using scanning electron microscopy (SEM) and Fourier transform infrared spectroscopy (FTIR). The effects of contact time，adsorbent dose，initial concentration of dye and pH on adsorption of RTB were investigated. The results indicated that the adsorption capacity increased with increasing contact time and reached equilibrium after 180 min. Raising temperature is beneficial for adsorption. The maximum adsorption capacity of modified cellulose from flax shive for RTB was 198.45 mg/g at 40 ℃. The adsorption capacity was large at high initial concentration of dye. The adsorption was significantly affected by pH of solution.
