AB  - The ability of unmodified and functionalized Carbon Nanotubes (MWCNTs) to capture
<i>Escherichia coli</i> 0157:H7 from water was tested and compared with Activated Carbon (AC). This study aims
to test the effectiveness of these materials to filter out this bacteria strain. Chemical oxidation was used to
functionalize MWCNTs to achieve the desired oxygenated functional groups which was analysed with Fourier
Transform Infrared spectroscopy (FTIR). Field Emission Scanning Electron Microscopy (FESEM) was used to
verify bacteria capture after water filtration on both functionalized and unmodified MWCNTs and AC,
respectively. Results showed that the bacteria were captured on functionalized MWCNTs and unmodified AC,
however, the bacteria were not detectable on unmodified MWCNTs and functionalized AC. The results indicate
that the presence of specific carboxyl functional groups on the surface of functionalized MWCNTs and
morphology of the unmodified AC is relevant for <i>Escherichia coli</i> 0157:H7 capture.
