Abstract |
Asymmetric composite membranes of cellulose acetate (CA)/hydroxyapatite
(HA) are prepared using phase inversion method for the separation of water,
urea, glucose, and protein. Various concentrations of HA up to 15 wt% are dispersed
uniformly in the CA matrix. The pore size of the CA matrix is tunable by varying
the concentration of HA. The flux of water, urea and glucose is *7 times higher
while for BSA *12 times higher in CA/HA composite membranes than pure CA.
Similarly, water absorption capacity of CA/HA composite membranes are increased
owing to the incorporation of hydrophilic HA in CA matrix. Moreover, the retention
rates are also reasonable in CA/HA composite membranes depending on the difference
in porosity of the membranes. The permeation of urea is much higher in the
CA/HA composite membranes as compared to pure CA, which is more suitable for
hemodialysis. Thereby, such CA/HA composite membrane offers the potential to be
used in hemodialysis applications.
