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 abstractREMOVAL OF CONGO RED DYE FROM AQUEOUS SOLUTION BY DATE PALM LEAF BASEGhadah AlsenaniRemoval of dyes from wastewater is important for industry and environmental protection. The adsorption technique, using biomass is attractive method for environmental and economical reasons. This study studies removal of Congo Red dye (CR) from aqueous solutions by adsorption using date palm Leaf Base (LB). The adsorption of congo red dye CR onto LB has been examined in aqueous solution … …American Journal of Applied Sciences, Vol. 11, Issue 9 · 26 Jul 2014 · 7,768 accessesView PDFCite
Research ArticleOpen accessIn the abstractPREPARATION OF ACTIVATED CARBON FROM PALM OIL SHELL BY CHEMICAL ACTIVATION WITH Na2CO3 AND ZnCl2 AS IMPRENATED AGENTS FOR H2S ADSORPTIONKanokorn HussaroHydrogen Sulfide (H2S, rotten-egg) is one of the major environmental pollutants having its sources in natural and anthropogenic activities. It’s had smell gas produced by anaerobic digestion in acid condition from organic and inorganic compounds containing sulphur, presents dual problems of its toxicity and foul ordour. One of methods of its removal is adsorption. Activated carbon is a widely used … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 17 Jun 2014 · 8,480 accessesView PDFCite
Research ArticleOpen accessIn the abstractMODELING ISOSTERIC HEAT OF BANANA FOAM MAT USING NEURAL NETWORK APPROACHPreeda Prakotmak, Hataitep Wongsuwan, Somchart Soponronnarit, Somkiat PrachayawarakornInformation on the adsorption isotherm and the thermodynamic properties can assist in optimizing food processing operations such as drying, packaging and storage in the assessment of the quality of food. In this study, an Artificial Neural Network (ANN) was used for modelling the water activity/Equilibrium Relative Humidity (ERH) of banana foam mat under a range of values of the Experimental … …American Journal of Applied Sciences, Vol. 11, Issue 8 · 13 May 2014 · 6,945 accessesView PDFCite
Research ArticleOpen accessIn the abstractINFLUENCE OF INCUBATION PERIOD, TEMPERATURE AND DIFFERENT PHOSPHATE LEVELS ON PHOSPHATE ADSORPTION IN SOILA. Rajput, Q. A. Panhwar, U. A. Naher et al.Phosphorus (P) is the most important element after nitrogen but P sorption properties are poorly documented in many soils. In this study, P sorption capacity in relation to incubation period and temperature under various P levels were determined for two different soil series (Rustam and Miani). Phosphorus was added at 5, 10, 25, 50, 100, 250, 500 and 1000 µg … …American Journal of Agricultural and Biological Sciences, Vol. 9, Issue 2 · 13 Feb 2014 · 8,290 accessesView PDFCite
Research ArticleOpen accessIn the abstractINVESTIGATION OF THE GROUNDWATER SUITABILITY FOR IRRIGATION PRACTICES IN AN ARID REGION: CASE STUDYAhmed MuradGroundwater is an important source of acceptable water for irrigation in the arid regions and in particular in the United Arab Emirates (UAE). Demand for groundwater is increasing in the UAE due to population growth and significant economic advancement associated with political stability. As agricultural practices are the main land use in Al Hayer area, southeast UAE, majority of extracted … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 25 Jan 2014 · 7,425 accessesView PDFCite
Research ArticleOpen accessIn the abstractComparison of Bet and Water Adsorption TechniquesB. H. Diya’uddeen, I. A. Mohammed, B. Y. Jibril, I. M. BugajeThe effect of activated carbon surface area on the amount of fluid adsorbed is significant. Thus, the surface area of an adsorbent is an important factor. The use of the costly BET measurement method is the standard. However, water adsorption method was proposed as an alternate method. Nevertheless, results presented were for activated carbon prepared and surface areas reported were … …American Journal of Engineering and Applied Sciences, Vol. 6, Issue 3 · 28 Aug 2013 · 7,246 accessesView PDFCite
Research ArticleOpen accessIn the abstractBiosorption of Ternary Cadmium, Nickel and Cobalt Ions from Aqueous Solution onto Saccharomyces cerevisiae Cells: Batch and Column StudiesMaedeh Galedar, Habibollah YounesiThe aim of this study was to remove cadmium, nickel and cobalt ions from aqueous solutions using yeast, Saccharomyces cerevisiae, pre-treated with ethanol. The cells are immobilized using polysulfone in both batch and continuous systems. To optimize the adsorption capacity of the yeast biomass, a batch system was used to investigate the effects of initial pH, initial biomass dose and … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 1 · 18 Mar 2013 · 7,948 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption from Aqueous Solution Onto Natural and Acid Activated BentoniteLaila Al-Khatib, Feras Fraige, Mohammad Al-Hwaiti, Omar Al-KhashmanDyes have long been used in dyeing, paper and pulp, textiles, plastics, leather, paint, cosmetics and food industries. Nowadays, more than 100,000 commercial dyes are available with a total production of 700,000 tones manufactured all over the world annually. About 10-15% of dyes are being disposed off as a waste into the environment after dyeing process. This poses certain hazards … …American Journal of Environmental Sciences, Vol. 8, Issue 5 · 28 Aug 2012 · 8,417 accessesView PDFCite
Research ArticleOpen accessIn the abstractCharacterization of Egyptian Smectitic Clay Deposits by Methylene Blue AdsorptionSalwa D. Abayazeed, Essam El-HinnawiProblem statement: The characterization of smectitic clays has been traditionally made using physical and chemical methods which are time-consuming and require costly equipment.
