Transport Properties of CO2and CH4using Poly(ether-block-amide)/GPTMS Hybird Membranes

UiO-66-polyether block amide mixed matrix membranes for CO2 separation

Mixed matrix membranes containing metal-organic frameworks have attracted large attention owing to the combined advantages of high separation performance and easy processability. In this work, CO2-philic zirconium metal organic framework UiO-66 and UiO-66-NH2 nanocrystals were synthesized and embedded into polyether block amide (PEBA) polymer membranes for CO2 separation. It can be found that a...

Study the Transport Properties of Anion and Cation Exchange Membranes toward Various Ions Using Chronopotentiometry

The transport properties of various anion and cation exchange membranes were studied in different electrolyte solutions using chronopotentiometry technique to get insight about the influence of the counter ion on the transport properties of the membranes. The investigated samples include heterogeneous ion exchange membranes varying in the functionality of fixed charged gro...
