| Summary: | In the present work, polysulfone (PSf) ultrafiltration membranes were prepared by solution casting.
The effects of rice husk silica (RHS) on the surface properties of the PSf/Polyethylene glycol (PEG)
membrane were observed and investigated. Characterizations were conducted to determine the
membrane cross-section area and RHS distribution. The structure of RHS and morphology of
membrane were analyzed by using X-ray diffractometer (XRD) and scanning electron microscope
(SEM). XRD pattern showed that the amorphous silica was produced from rice husk ash (RHA).
The analysis of SEM indicates that the addition of RHS obviously changed the microstructure of the
membrane especially at top layer and sub layer. |
