Potensi Zeolit Alam Sebagai Antioksidan
(2012)
Zeolite is an aluminosilicate mineral which are three dimensional frameworks in its structure, has cavities and channels connected to each other creating wide surface so that effective as an adsorbent. Besides, zeolite has ...
Komposit Oksida Besi Magnetit-Zeolit Lampung sebagai Adsorben Cr(III) dan Cr(VI)Composite of Magnetite Iron Oxide-Lampung Zeolites as Adsorbent for Cr(III) and Cr(VI)
(2012)
Composites of magnetite iron oxide-zeolite were made to obtain adsorbents which were responsive to the magnetic field so as it can be readily separated from the adsorbate medium after the process of adsorption. Iron oxide ...
Sintesis Hidrotermal dan Karakterisasi Kristal Titanium Dioksida (TiO2)
(2012)
The aim of this research is studied about methode and temperature effect to phase and size of titanium dioxide (TiO2) crystal. Titanium dioxide (TiO2) crystal was synthesized by hydrothermal method with mixed of TiO2 powder ...
Sintesis dan Pencirian Surfaktan Nonionik Berbasis Poliol dari Onggok dan Asam Oleat
(2012)
Processing of cassava into tapioca starch produces onggok that can be liquefied to produce polyols. The esterification of liquefied products with oleic acid produced esters that can be used as surfactant. Polyol was prepared ...
Analisis Kestabilan Model Infeksi Virus Hepatitis B dengan Pertumbuhan Hepatosit yang Bersifat Logistik
(2012)
This manuscript discussed a mathematical model to describe the dynamics of population of hepatocytes and hepatitis B virus developed by Eikenberry et al. (2010). This model uses a logistic hepatocytes growth model of ...
Kitosan Tertaut Silang Urea-Formaldehida dan Asam Sulfat Sebagai Penjerap Cibacron Red
(2012)
Modified chitosan cross-linked with urea-formaldehyde and sulfuric acid has been prepare through an establishment of cross-linker material of urea, formaldehyde, and sulfuric acid with the ratio 1:2:1. The ratio of ...
Adsorpsi ion Cr(III) dan Cr(VI) menggunakan bentonit alam termodifikasi oksida besi
(2012)
Speciation of trivalent and hexavalent chromiums is important to do because both have very different characteristics. Hexavalent chromium is toxic meanwhile trivalent chromium is needed in metabolism. The aim of this study ...
Sintesis Polimer Superabsorben Onggok Tapioka-Akrilamida: Pengaruh Konsentrasi Monomer dan inisiatorSynthesis of Superabsorbent Polymer Obtained from Cassava Waste Pulp-Graft-Acrylamide: Effect of Monomer and Initiator Concentration.
(2012)
Cassava waste pulp (CP) is a solid waste product from tapioca processing industry. This waste still contains high carbohydrates, so it can be modified into superabsorbent polymers (SAP) through grafting and crosslinking ...
Zeolit Alam Teraktivasi Basa untuk Pemurnian BioetanolBased-activated natural zeolite for bioethanol purification
(2012)
Utilization of bioethanol in mixing with fossil fuel greatly depends on its purity. To get high purity, adsorptive separation method with zeolite as adsorbent had been developed. Both natural and synthetic zeolite could ...
Pencirian Elektrode Membran Termodifikasi Zeolit untuk Pengukuran Kromium(VI)Characterization of Zeolite-Modified Membrane Electrode for Measurement of Chromium(VI).
(2012)
This research success fully made zeolite-modified membrane electrodes for measurement of Cr(VI). Zeolites used were mordenit type with particle size of 414.3 nm. Ion selective electrodes (ISE) were made with membrane ...
