ABSTRACT
The montmorillonite (MMT) nanoparticles as patchouli oil bleaching has been prepared from the isolated MMT of Aceh Tamiang bentonite. MMT in bentonite powder was isolated through a top-down isolation method by ultrasonication, sedimentation and high energy milling process. As many as 14% of MMT was successfully isolated and characterized via XRF and XRD. XRF analysis on the composition of isolated MMT indicated that the major composition of MMT are Si (24.76%) and Al (16.37%). From XRD pattern, the two theta (2θ) peak of MMT are about 19.85°, 20.30° , 26.62 and 50.15° that was identified as MMT (empirical formula (Si7.80Al1.72Cs0.16Fe0.20Mg0.28O20.00)), indicating the success of the isolation process. Furthermore, based on the results calculated using XRD with Scherer’s equation, the size of MMT was 0.42 nm and the derived lattice constant was 4.20 Å. Moreover, the MMT nanoparticles exhibited as a good Patchouli Oil Bleaching material to reduce colors in oil.
