  • 摘要: 研究了颗粒活性炭(GAC)对苯酚的吸附能力,确定GAC的吸附平衡时间,探讨超声波再生吸附苯酚活性炭的影响因素。实验结果表明:6 h后GAC吸附100 mL浓度为250 mg/L的苯酚水样达到平衡,最大平衡吸附量为16.24 mg/g,去除率为70.5％。再生条件为再生液温度30℃,超声再生时间20 min,解析液为0.25 mol/L氢氧化钠溶液,此时GAC再生效果为86.1％。
    Abstract: The adsorptive capacity of granular activated carbon (GAC) to phenol was studied, and the time of GAC adsorption balance was determined.It also investigates ultrasonic regeneration’s influencing factors to GAC adsorbing phenol. The experiment results showed that the GAC adsorbed 100 mL phenol water whose concentration was 250 mg/L and then reached balance after 6 h.The maximum amount of balance adsorption was 16.24 mg/g and the removal rate was 70.5%.The regeneration conditions are as follows: liquid temperature of 30℃,the ultrasonic regeneration time of 20 min, and the analytical sodium hydroxide solution of 0.25 mol/L. The regeneration efficiency of GAC is 86.1% under the above conditions.
