Research ArticleOpen accessIn the keywordsAdsorption of Nickel and Zinc by Residual SoilsNur ’Aishah Zarime, W. Y. Wan Zuhairi, Sivarama KrishnaSoil has long been utilized as low cost liner material to prevent contamination from leachate to groundwater media. To find a suitable soil material for this purpose is a great challenge. This study describes the potential use of residual soil to functions as engineered clay liner for waste disposal landfill in Malaysia. Three types of residual soils were investigated namely … …American Journal of Environmental Sciences, Vol. 10, Issue 6 · 5 Dec 2014 · 7,116 accessesView PDFCite

Parameters … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 7,605 accessesView PDFCite
Research ArticleOpen accessIn the abstractYeast Immobilization on Peanut Hulls for Potential Application in Beer FermentationWaldir D. Estela-Escalante, Sergio Rosales-Mendoza, Mario Moscosa-SantillánThe potential of using peanut hulls as support material for immobilization of yeast cells during beer fermentation was evaluated. After treatment of peanut hulls with 0.5% (w/v) NaOH, FTIR analysis revealed an important change on its chemical composition. For instance, the proportion of lignin decreased and as a result the adsorption of yeast cells onto the support material during fermentation … …American Journal of Biochemistry and Biotechnology, Vol. 15, Issue 3 · 22 Jul 2019 · 8,375 accessesView PDFCite
Research ArticleOpen accessIn the abstractWater Filter Fabrication from a Mixture of KMnO4 Modified Kapok Carbon Fiber, Zeolite, Bentonite and Clay for Fe3+Removal and Water Hardness TreatmentKannika Thongdee, Kalayaporn Parun, Suphakrit Benjatitmongkhon et al.A water filter was fabricated from a mixture of KMnO4 modified kapok carbon fiber, zeolite, bentonite and kaolinite clay for Fe3+ removal and water hardness treatment. The effects of amount of KMnO4 modified kapok carbon fiber (30-60 wt%), zeolite (20-40 wt%) and sintering temperature (500-700°C) on the properties of sintered products were evaluated. The best of sintered products were tested … …American Journal of Applied Sciences, Vol. 14, Issue 6 · 15 Jun 2017 · 7,580 accessesView PDFCite
Research ArticleOpen accessIn the abstractInvestigation of Methylene Blue Dye Adsorption from Polluted Water Using Oleander Plant (Al Defla) Tissues as SorbentRajab Abu-El-Halawa, Sami A. Zabin, Hamzah H. Abu-SittahThe main purpose of this research was to investigate the ability of Oleander plant (Al Defla) tissues to adsorb Methylene Blue (MB) dye from polluted water. The experiments were carried out through batch-adsorption technique to investigate the influence of the following experimental parameters on adsorption process namely, adsorbent quantity, MB initial concentration, adsorbent particles size, ionic strength, pH and temperature. … …American Journal of Environmental Sciences, Vol. 12, Issue 3 · 4 Jun 2016 · 7,994 accessesView PDFCite
Research ArticleOpen accessIn the abstractINCREASING ADSORPTION OF ACTIVATED CARBON FROM PALM OIL SHELL FOR ADSORB H2S FROM BIOGAS PRODUCTION BY IMPREGNATIONWasan Phooratsamee, Kanokorn Hussaro, Sombat Teekasap, Jongjit HirunlabhBiogas is the combustible gas produced through a biological process, known as anaerobic digestion which is the process operated at low-temperature and without air. Biogas consists of 55-80% CH4, 20-45% CO2 with trace amount of H2S and other impurities. Common H2S removal technologies from biogas fall into one of adsorption on a solid such as iron oxide based materials, activated … …American Journal of Environmental Sciences, Vol. 10, Issue 5 · 16 Aug 2014 · 7,670 accessesView PDFCite
Research ArticleOpen accessIn the abstractCHARACTERIZATION OF OIL PALM EMPTY FRUIT BUNCH AND RICE HUSK BIOCHARS AND THEIR POTENTIAL TO ADSORB ARSENIC AND CADMIUMNorazlina Abu Sari, Che Fauziah Ishak, Rosenani Abu BakarBiochar as a new soil amendment has a potential in controlling the fate of trace elements in the soil system. However, the production of biochar from different feedstocks and pyrolysis conditions resulted in variable biochar properties which have an influence on trace elements availability. The experimental works are focused on physical and chemical properties of biochars produced from Empty Fruit … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 3 · 13 Aug 2014 · 10,585 accessesView PDFCite
