novel and simple method is introduced for rapid and
highly efficient water treatment by reverse osmosis (RO) method using
multiwalled carbon nanotubes (MWCNTs) polyacrylonitrile (PAN)
polymer as a flexible, highly efficient, reusable and semipermeable
mixed matrix membrane (MMM). For this purpose, MWCNTs were
directly synthesized and online purified by chemical vapor deposition
(CVD) process, followed by directing the MWCNT bundles towards an
ultrasonic bath, in which PAN polymer was simultaneously suspended
inside a solid porous silica support in water at temperature to 70 οC.
Fabrication process of MMM was finally completed by hot isostatic
pressing (HIP) process. In accordance with the analytical figures of
merit, the efficiency of fabricated MMM was 97. The rate of water
treatment process was also evaluated to 6.35 L min1. The results reveal
that, the CNTbased MMM is suitable for rapid treatment of different
forms of industrial, sea, drinking and well water samples.
