Adsorption Separation of Copper (Ⅱ) from Anhydrous Alcohol Using Zwitterionic Hybrid Membranes
A series of novel zwitterionic hybrid membranes were prepared by crosslinking 3-aminopropyltriethoxysilane (APTES)with chloroactic acid (ClCH2COOH).The thermal stabilities of these hybrid membranes were determined using TGA and DSC analysis.Their application for copper (Ⅱ) removal from anhydrous alcohol was discussed.TGA thermal analysis shows that they have high thermal stabilities and their degradation temperature (Td) at 10 % weight loss elevates with the addition of ClCH2COOH in them DSC measurement indicates that the melting temperature of hybrid membranes A-D reveals a downward trend as the amount of C1CH2COOH.Adsorption experiment evidences that copper (Ⅱ) can be removed from anhydrous alcohol using these zwitterionic hybrid membranes.These findings suggest that these zwitterionic hybrid membranes are promising adsorbents for the removal of heavy-metal ions from non-aqueous system.
