Karakteristik Silika Sekam Padi Tergrafting 4-Vinil Piridin
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 Cu2+ adsorption from solution, and the ability of the sample
to inhibit the microorganism growth.
