碩士 === 國立雲林科技大學 === 化學工程與材料工程系 === 102 === The purpose of this thesis is to investigate the electrospinning technique of nano-sized new webs. By using electrostatic spinning, the adsorption capacity of the webs which have high specific surface area and porous structure is enhanced for the applications of removing heavy metal and dyes. In this study, we use two kinds of material which are carboxymethyl-β-cyclodextrin (CM-ß-CD) and poly methylmethacrylate (PMMA) to get nano webs. In copper ion adsorption experiments, the maximum absorbtion is 163.7 mg/g. In dye adsorption experiments, the maximum absorbtion is 308.46 mg/g, when the pH of dye solution is 12. In this paper, the possible adsorption mechanisms are also explored using isotherm equations and kinetic models. The present study shows that the adsorbent has high adsorption activities for waste water.
