英语翻译
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.
