Homogeneous high-concentration CS solutions and high-strength CS hollow-fiber membranes were successfully prepared.The novel dilute-dissolution and evaporating-concentration method developed in this study allowed homogeneous CS solutions with a concentration at as high as 18 wt % to be practically obtained.This overcame the limitation of the conventional preparation method,which fails to obtain a high-concentration CS solution with homogeneity.From the prepared high-concentration CS solutions,CS hollow-fiber membranes with comparable or even higher mechanical strengths (in the wet state) than many industrial synthetic polymer membranes were fabricated.The prepared CS hollow-fiber membranes were found to have a porous and macrovoid-free structure on the cross section and inner surface but a much denser outer surface.This type of membrane structure may be beneficial for a membrane used to achieve both the filtration (the removal of larger particles) and adsorption (the removal of dissolved small components) separation functions.Adsorption experiments showed that the prepared CS hollow fibers had a very high adsorption capacity for copper ions.The low crystallinity of CS achieved in the prepared hollow fibers is considered to be one of the major factors that contributes to the high adsorption capacity.The prepared CS hollow fibers were also shown to effectively remove copper ions from real wastewater from the semiconductor industry.It is expected that there will be great potential for CS hollow-fiber membranes to be used in many separation applications in the future.

高浓度CS方案和强度均中空纤维超滤膜偷袭了.这部小说dilute-dissolution和evaporating-concentration方法允许在这个研究开发与浓度均CS解的股份是几乎获得了.这个克服了传统的制备方法的局限性,而未能得到高浓度CS解性.从准备高浓度溶液,CS中空纤维超滤膜CS类似甚至更高的机械强度在潮湿的状态)比许多工业合成聚合物膜是编造的.中空纤维超滤膜法制备的c被发现有一种多孔结构和macrovoid-free截面内表面,但很多,致密外表面.这种类型的膜结构可能是有益的,用来实现两者膜过滤(除去大颗粒)、吸附去除溶解的小部件)分离功能.实验结果表明,该吸附准备了中空纤维膜CS很高的吸附能力为铜离子.较低的结晶度的CS取得了中空纤维膜准备被认为是一个主要的因素导致了高的吸附量.预备CS中空纤维膜也被证明有效的去除铜离子与真正的半导体工业废水.预计将有巨大的潜力中空纤维超滤膜CS用于分离应用.
