dc.description.abstract | Grafting copolymerization of acrylamide (AAm) on cellulose derived from sago fibers (α-cellulose 78.61%) has been performed by using N,N'-methylene-bis-acrylamide (MBA) as cross-linker and ammonium peroxydisulfate as initiator. The cellulose-g-polyacrylamide copolymer products were characterized by their water absorption capacity, grafting ratio, and grafting efficiency as the initial characterizations. Further characterizations was carried out by using infrared spectroscopy, electron microscopy imaging, and X-ray diffraction techniques. The characterization results showed that the copolymers has been formed. Synthesis modification by sequential addition of AAm and MBA, and increased concentration of MBA reduced the water absorption capacity, whereas the grafting ratio and efficiency were increased. Copolymer products could be applied as a stationary phase for normal-phase column chromatography, based on the porous surface morphology as well as good resistance against n-hexane, n-pentane, and cyclohexane solvents. | en |
