摘要
文章从微孔性、断裂强度、疏水性、膜阻等几个方面对三种PVDF中空纤维膜进行了表征与性能评价,选出了最适宜提溴操作的PVDF中空纤维膜。通过海水提溴实例验证了评价结果。此研究方法为提溴用中空纤维膜的选择提供了理论基础。
Three kinds of PVDF hollow fiber membrane was characterized and evaluated from microporosity, breaking strength, contact angle, and membrane resistance etc. The suitable PVDF hollow fiber membrane for bromine extraction operation was selected. And the results was testified by bromine extraction experiment from brine. The study provides theoretical foundation for selection of hollow fiber membrane used for bromine extraction.
