渗透蒸发脱除水溶液中挥发性有机物

摘要制备了用于渗透蒸发的聚二甲基硅氧烷 (PDMS)硅橡胶膜 ,考察了其从水溶液中脱除苯和氯仿的渗透蒸发性能。分析讨论了料液浓度、温度和雷诺数等因素对膜渗透蒸发性能的影响。本研究中所制备的渗透蒸发膜的分离性能优于国外文献值

Abstract： In this paper, the PDMS silicon rubber memberanes has been prepared.The pervaperation performance of the memeranes for removing benzene and chloroform from water is studided.Then we find that the separation perfermance is better than literature abroard.Lastly according to feed concentrations,feed temperatures and feed Reynold's numbers,we discuss the factors that affect the pervaperation performance of the memeranes.
