基于管式陶瓷载体的碳化ZIF-67掺入PDMS混合基质膜及其渗透汽化回收乙醇应用
Carbonized ZIF-67 incorporated PDMS mixed matrix membranes on ceramic tubes for recovery of ethanol via pervaporation
摘要
Abstract
It is a very effective strategy to prepare mixed matrix membranes(MMM)by incorporating hydrophobic nanoparticle into the polymer matrix to improve the pervaporation separation performance in the process of recovering ethanol from aqueous solution.In this study,polydimethylsiloxane(PDMS)based MMM filled with ZIF-67 particles was prepared on ceramic tubes,but there were some associated problems such as severe reunion,poor compatibility,etc.In order to improve the diffusion process,ZIF-67-derived nanoporous carbon(C-ZIF-67)was prepared to replace ZIF-67 in conventional MMM.ZIF-67 and carbonized particles were studied by various characterization,and the morphology and properties of MMMs were tested.Compared with ZIF-67/PDMS MMM and pure PDMS membrane,C-ZIF-67/PDMS MMM exhibited better enhanced separation performance:the best performance with a total flux of 1.04kg/(m2·h)and a separation factor of 9.2 at 60℃for 5%ethanol solution.In summary,the relevant experimental results had preliminarily indicated that C-ZIF-67/PDMS MMM had potential application value in the separation of dilute ethanol aqueous solution.关键词
