摘　　要：采用国产FA 弱碱性离子交换纤维作吸附滤料 ,测试了FA 纤维对HF气体的动态吸附容量 ,探讨了动态吸附的影响因素 ,考察了FA 纤维的再生效果。结果显示 ,FA 纤维对HF气体的穿透吸附量为 75mg g,饱和吸附量为 1 52mg g。该滤料经多次再生循环使用 ,吸附效果没有明显变化 ,说明FA 纤维具有很好的化学稳定性。The dynamic adsorption capacity of HF gas utilizing domestic FA weak basic ion exchange fiber as adsorbent is studied. Also, the factors influencing dynamic adsorption are investigated and the re adsorption effect of HF gas is tested. The results showed that the pierce through adsorption amount of HF by ion exchange fiber is 75 mg/g, and the saturated adsorption amount of HF by the fiber is 152 mg/g. There is no obvious change in adsorption effect after a repeated 5 run regeneration of the fiber, showing its good chemical stability.
