| dc.description.abstract | Nanoparticle of magnesium silicate from silica rice husk use oleic acid has been
synthesized. This synthesis is carried out by extracting silica from rice husk with
alkalis method using NaOH 10% and then added MgO. Magnesium silicate obtained
then added the oleic acid which acts as a template and calcined at a temperature of
900oC for 4 hours then defined that character. Characterization using XRD showed
crystal diffraction peaks of MgO, MgSiO3 and Mg2SiO4. Spekturm FT-IR showed a
group of Si-O-Si and Si-OH indicating magnesium silicate material. The results of
nitrogen adsorption desorption of magnesium silicate using oleic acid shows the pore
size, pore volume, surface area and particle size, respectively: 2,1048 nm, 0,017450
cm3/g, 62,1099m2/g and 96,6030 nm. This result is in contrast to the results of nitrogen
adsorption desorption magnesium silicate without using oleic acid, the results is:
2,1106 nm, 0,001240 cm3/g, 3,3330 m2/g and 1.800,2003 nm. From this research it
was found that by using oleic acid as a template material can produce nanoparticles of
magnesium silicate. | en_US |
