ABSTRACT
This study was carried out to investigate the grafting of4-Vinyl Pyridine (4-VP) on silica prepared from rice
husk, with the main aim to study wether the 4-VP grafted retains its characteristics. For this purpose, the grafted
silica was analysed using FTIR spectroscopic method, followed by testing of the sample for solvent adsorption, Cu2+
adsorption from solution, and bacterial inhibitions, since 4-VP has been known to possess such properties. The
FTIR analysis revealed that under the experimental conditions applied, the 4-PV was well grafted onto silica surface.
The success of grafting was also supported by the results of solvent adsorption, which indicate the increase in
adsorption capacity with increased percent of grafting and higher adsorption capacity toward polar solvent. The
same supports are also provided by the ability of the sample to adsorp results of cif+ adsorption from solution, and
the ability of the sample to inhibit the microorganism growth. .
Keywords: Graft copolymerization, rice husk silica, 3-methacryloxypropyltrimethoxysilane, 4-vinyl pyridine,
microorganismgrowth inhibition. |
