Abstract: Synthesis and
characterization of composite membranes using the precursor of khitosan,
silica, and calcium carbonate (CaCO3) have been carried out. Visual
observations indicated that at pH 7 the formation of membrane depends on
khitosan and calcium carbonate composition. FTIR analysis confirm the
availability of absorption of –OH at
3400 cm-1, amine at 1600 cm-1and Si-O-Si at 1080 cm-1.
Futhermore, the existence of carbonate have been detected from XRD pattern where
their crystal size increase due to the addition of more calcium content.
Keywords: composite membranes,
