摘要
研究了活性炭纤维(简称ACF)处理含酚模拟废水的静态吸附最佳工艺条件,测定了不同温度下的吸附等温线,并在相同条件下比较了ACF和活性炭的吸附性能。结果表明,ACF对苯酚的吸附容量为248mg/g,吸附饱和后经多次再生吸附容量几乎不变,吸附性能比活性炭好。室温时,在酸性或中性条件下,向100mL浓度为282mg/L的含酚模拟废水投加活性炭纤维0.5g,恒温振荡30min,苯酚去除率可达91%。
The optimal cond itions ofwaste water treatment of simulated waste water containing phenol in static state by activated carbon fiber (ACF) are stud ied. The isotherms are measured at d ifferent temper- atures and adsorption capacities of ACF and activated carbon under the same cond itions are compared. The results ind icate that, the adsorption capacity ofACF is 248 mg/g which is much better than that of activated carbon. When 0. 5 g ofACF is added into 100 mL of simulated waste water containing phenol with concentration of 282 mg/L, soaked and shaking for 30 m in at room temperature and under acid ic or neutral cond ition, the removal rate of phenol can reach 91% and saturation adsorption efficiency reaches
