摘要

現今的生活中，水時常受到金屬離子的污染，當引用污染水後，對人體造成不良影響，所以本研究以聚丙烯腈（PAN）製備靜電紡絲液，透過加入乙二胺四乙酸四鈉鹽（EDTA-4Na）進行混練，探討其纖維結構、表面形態，並評判應用在過濾水中金屬離子之效果，研究結果顯示，靜電紡絲纖維在加入EDTA-4Na粉體後其纖維直徑為0.47微米較未加入EDTA-4Na粉體之直徑0.44微米粗，但EDTA-4Na粉體仍有效的附著於纖維上，並於吸附測試中顯示於180分鐘時吸附率達34.37%，表示過濾膜具吸附水中重金屬之功效。

Water of nowadays is often contaminated by metal ions. Due to these contaminants, if polluted water supports a human use, such as drinking water, may occur adverse health effect .Therefore, this research is dedicated to making the excellent quality water filter. In this study, N,N-Dimethylacetamide (DMAc) is used to dissolve polyacrylonitrile fibers (PAN) in preparation for electrospinning solution, and then mix it into Ethylene Diamine Tetra Acetic Acid -4Na (EDTA-4Na).At last, compare the fiber structure and the surface morphology of the result with polyacrylonitrile fibers (PAN) to conclude the effect of filtering metal ions in water. The results show that the fiber diameter of the electrospinning fiber after adding EDTA-4Na powder is 0.47 micrometers, which is more than the ideal 0.44 micron diameter of the electrospinning fiber without EDTA-4Na powder. However, EDTA-4Na powder is still effectively attached to the fiber, and has a nanometer level, and the adsorption rate is shown to be 34.37% at 180 minutes in the adsorption test, indicating that the filter mold has the effect of adsorbing heavy metals in water.
