摘要

Abstract

Desalination is considered a viable method to overcome the issue of water scarcity either from waste water or seawater. For this purpose

this study employed a facile approach to develop surface immobilized oxidized-MWCNTs (o-MWCNTs) onto crosslinked polyvinyl alcohol (PVA) membrane. Firstly

modified polysulphone substrate was synthesized on to which crosslinked PVA layer was spread onto it. PVA layer act as active layer for surface immobilization of o-MWCNTs in varying concentration. The functional group analysis

morphology and roughness of membranes surface was conducted out using FTIR

SEM and AFM respectively. The results showed that modified membranes

immobilized o-MWCNTs enhanced the salt rejection (Na

) upto 99.8%. After contacting with

Escherichia coli

and

Staphylococcus aureus

for 2.5 h the bacteria mortalities of the fabricated membrane could reach 96.9%. Furthermore

the anti-biofouling tests showed that OP-MWCNTs (1–5) modified membranes have higher anti-biofouling property than the control membrane.
