活性炭纤维对凝结水中Fe^(3+)的吸附研究

Absorption of Fe^(3+) from the Condensed Water by Activated Carbon Fibers

通过静态吸附和动态吸附实验,考察了活性炭纤维(ACF)对Fe3+的吸附性能,研究了不同实验条件下的动态吸附穿透曲线;通过扫描电镜,观察了吸附前后ACF的表面形貌.结果表明:ACF对Fe3+的吸附既有物理吸附又有化学吸附;随着ACF比表面积增大或吸附溶液温度升高,对Fe3+的吸附容量增大;动态吸附时,当流速为10 m L/min,最有利于出水达标.

The absorption performance of Fe3^＋on the surface of activated carbon fibers（ACF） was investigated by static and dynamic absorption experiments. The breakthrough curves of dynamic absorption in various experimental conditions were studied,and the surface morphology before and after Fe3^＋absorption of ACF were investigated by scanning electron microscopy（SEM）. The results show that the absorption process is composed of physical absorption and chemical absorption,and that the absorption capacity can be improved by increasing the surface area of ACF and the temperature of the reaction solution. In the dynamic absorption process,the treated water of the best quality is obtained when the flow rate is of10 m L / min.
