Pengaruh Impregnasi Logam Titanium Pada Zeolit Alam Malang Terhadap Luas Permukaan Zeolit

Abstract

<p>Effort that can maximize the working of natural zeolite is by activation and modification as a carrier of active metals or commonly called impregnation. Modified zeolite by impregnation using titanium metal is to increase the performance of a pure metal catalysts such as low in thermal stability, decreasing surface area and sintering occurs (clotting) and expensive in the application. Bearers Treatment in the metallic solids by impregnating the zeolite would make the metals in zeolites as bifungsional catalysts.</p><p>Modified Malang’s natural zeolite starting with the activation process using a solution of NH<sub>4</sub>NO<sub>3</sub> 2 M, continued by the addition of titanium metal used in zeolite TiO<sub>2</sub> solution with a concentration of 0.1, 0.2, and 0.3 M. Modified zeolite crystallinity characterized analized by XRD analysis. Methylen blue adsorption on Ti-zeolite is to measure the specific surface area. SEM surface morphology analysis is used to determine the content of the element is by using XRF analysis.</p><p>Characterization using XRD analysis results indicate that Malang’s natural zeolite not changed in the structure, but it changes the intensity due to the addition of titanium. The largest surface area measurement obtained from the treatment of Ti-zeolite 0.1, 0.2 and 0.3 M are : 23.159; 23.077 and 20.848 m2/gr. SEM analysis showed that titanium metal dispersion fairly evenly after the modification. While from the XRF analysis showed that the ratio of Si / Al increased to 4.354 and content of titanium in the Ti-natural zeolite Malang is 13.6%.</p>

Preparation and Characterization of Catalyst Zn/Al2O3 Catalyst Using Dry and Wet Impregnation Method

“…In Figure 5, sample B1 shows the highest spectrum intensity around 1650, while samples A1 and B2 as shown in Figure 4, and 6 are 800 and 1400. The difference in intensity of these three materials show differences in the amount of metal contained in the sample [13]. This reinforces the results of the AAS test on the three samples where B1 sample with the highest intensity does have the highest metal content compared to all samples.…”

Effect of Additional Polyethylene Glycol and Citric Acid on Characteristics of NiMo/g-Al2O3 Catalyst in Light Cycle Gas Oil Hydrodesulfurisation

“…Based on the active metal content of the catalyst 3), the catalyst with the addition of PEG and CA has a higher metal content. It indicates that the Mo metal is well dispersed into the pore support, causing a reduced surface area [43]. Okamoto et al stated that the surface area of the catalyst for the hydrotreating process is at least 150 m 2 /g so that the catalyst, with the addition of PEG and CA, can still be employed for the hydrotreating process [40].…”

BIOSINTESIS NANOPARTIKEL PERAK (AgNPs) DENGAN EKSTRAK DAUN KIRINYUH (Chromolaena odorata) TERIMPREGNASI ZEOLIT DALAM MENGHAMBAT BAKTERI PENYEBAB JERAWAT

“…Penggunaan zeolit yang memiliki potensi untuk dikembangkan menjadi semacam masker wajah sebenarnya telah banyak dilakukan, namun masih sangat sedikit penelitian yang mengarah ke penggunaannya dalam bidang kosmetik atau kesehatan. Selain itu, kemampuan adsorbsi yang besar disebabkan oleh morfologi kristal pada zeolit berupa rongga-rongga yang saling berhubungan sehingga permukaan zeolit menjadi luas (Rianto et al, 2012) dan cenderung ramah digunakan pada penggunaan luar seperti masker wajah oles. Pada penelitian (Amalia & Purwamargapratala, 2017) penggunan zeolit sebagai stabilisator mampu mempertahankan kemampuan aktivitas antibakteri dari formula ekstrak terhadap pemanasan suhu 38°C selama 24 jam.…”
