| 摘 要： | 利用亚硫酸氢钠和碳酸钠改性的活性炭对室内空气污染中甲醛进行了治理研究,考察了颗粒活性炭、粉末活性炭、改性活性炭对甲醛去除率的影响。测试了改性活性炭的平衡吸附量,吸附穿透时间。结果表明,亚硫酸氢钠和碳酸钠改性的活性炭对甲醛的去除率为60%,动态治理后能够达到国家室内空气质量标准。并通过扫描电镜图谱分析了改性活性炭的吸附机理。

| Abstract: | Formaldehyde from indoor air is treated by modified activated carbon. The effects on formaldehyde adsorption efficiency were investigated, and adsorption curve of modified activated carbon was measured. Results indicated that activated carbon modified by NaHSO3 and Na2CO3 can adsorb formaldehyde over 60%, which can meet indoor air quality standard. The adsorption mechanism of the modified activated carbon was also described through scan electron microscopy. |
