Isolation and Characterization Montmorillonite Nanoparticles of Aceh Tamiang Bentonite as Patchouli oil Bleaching

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.

Conversion of Palm Oil to Biodiesel Using TiO2/Monmorillorite (MMT) Composite Catalyst from Aceh Tamiang Bentonite

“…The XRD strength plot for a TiO2/MMT composite sample as a function of 2θ is shown in Figure 1. According to XRF findings in previous studies, MMT (JCPDS 96-901-0958) includes SiO2 (Si = 25.04 wt.%, O = 45.71 wt.%), which is more dominant than Al, Fe, Ti, Ca, K, S [8]. This indicates that in MMT, low SiO2 crystals are more commonly associated with the quartz process (JCPDS 96-900-9667).…”

“…In addition, using ZnO in bentonite, a biodiesel conversion of 88% of soybean oil was achieved [7]. Monmorillorite (MMT) has also been synthesized from bentonite for the purification of patchouli oil [8]. Bentonite is a local potential as a catalyst material in the study of biodiesel conversion from vegetable oils, such as palm oil, in Aceh Tamiang, Aceh, Indonesia.…”

Pengaruh Interkalasi Mikro Montmorillonit Dengan Mikro Kitosan Sebagai Adsorben Untuk Meningkatkan Mutu Minyak Nilam

“…Filtratnya ditampung dan dikeringkan menggunakan oven sampai seluruh akuades menguap. Filtrat yang sudah kering sebagai fraksi 4 (Harmawan et al, 2019;Wahyudi, 2010). Fraksi 4 ditumbuk menggunakan alat High Energy Milling (HEM) kemudian dianalisis dengan alat Particle Size Analyzer (PSA) untuk menentukan ukuran Montmorillonit yang terbentuk.…”

Production of Biodiesel Through Transesterification of Crude Palm Oil (CPO) Using Montmorillonite Nanoparticles (Nano-MMT) as Heterogeneous Solid Catalyst

“…Nano-MMT is the main content of bentonite [14,15] that has unique properties because it has a very small particle size, resulting in a very high surface area [2,13]. Besides, with a very fine size, the characteristic properties of the element will appear and can be engineered like as the properties of magnetism, optics, electricity, thermal, and others, so that their utilization has penetrated various fields of human life, such as health, information, transportation, industry, energy and catalyst [16].…”
