Preparation of Ti-based Hybrid Membranes and Its Application for the Removal of Copper(Ⅱ) Ions from Water
A series of Ti-based hybrid membranes were prepared via sol-gel reaction using tetrabutyl titanate,Ti(OBu)4 and tetraethyl orthosilicate (TEOS) as hybrid precursors.TGA and DSC thermal analyses revealed that these hybrid membranes have high thermal stability.Contact angle measurement shows that with an increase of Ti ingredient in hybrid membranes,their hydrophilicity decreased.The change in the surface color of sample adsorbed Cu(Ⅱ) evidences that these Ti-based hybrid membranes can be used as adsorbents to adsorption separation copper (Ⅱ) ions from Cu-bearing water.
