Removal of Toxic Gases on Strong/and Weak-Base Anion Exchange Fibers

다국어 초록 (Multilingual Abstract)

In this study. a strong base ion exchange fiber, APP-g-GMA, was synthesized by grafting GMA onto a PP trunk polymer, using an E-beam accelerator for the purpose of pre-irradiation, in order to remove sulfur dioxide and nitrogen dioxide. A weak-base ion exchange fiber, AN-co-MMA, was spun by wet-spinning and was functionalized by hydrolysis. To determine the effects of various conditions, such as the SO₂ and NO₂ concentrations and the water content in the column, we investigated the adsorption for SO₂ and NO₂ over two types of fibrous ion-exchangers. The adsorption rate constants were calculated from macroscopic models by a linear square fitting method. SO₂ and NO₂ removal on the fibrous ion-exchangers both depend on the initial concentration of SO₂ and NO₂. The removal efficiency of NO₂ and SO₂ on the weak-base anion exchange fiber was slightly affected by initial water contents of ＞ 10 g. Also, the removal efficiency of NO₂ on the strong-base ion exchange fiber was slightly dependent on the initial water content at a water content of ＞ 20 g.
