A-11 DNA奈米纖維的成形條件及其對染料吸附性之探討 DNA nanofibers of molding conditions and its effect on adsorption of the dye research 1 *1 (70%) (30%) 1 1 *1 Z. Y. Ye , C. P. Chang Department of Textile Engineering, Chinese Culture University1 摘要 DNA (DNA) (PVA)DNA DNA 18kV 15cm 0.8ml/hr 10 wt%PVA/DNADNA DNA 10 wt%PVA 10%DNA 240min86.74% Abstract This study aim at using the characteristic of heavy metal compound which embededin deoxyribonucleic acid(DNA) the double helix structure to purity wastewater from industry. Inorder to develop adsortoble DNA filter material, DNA polymer solution mixed with polyvinyl alcohol(PVA) in electrostatic spinning. its large surface area, adsorption wide area.The results point out indeed when 10wt%PVA/DNA mixture condition obtained the better DNA nanofibers morophorge. Along with DNA solution concentration enhanced adsorption rate, the best DNA nanofibers mixture condition was 10D 10P. The adsorption effect was and after 86.74% after 240 minutes reached absorption equilibrium state. 關鍵詞：去氧核醣核酸、靜電紡絲、聚乙烯醇 Keyword: DNA, Electrostatic spinning, PVA 一、前言 Formals [1]
