Research ArticleOpen accessIn the keywordsInvestigation 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 abstractKMnO4 Modified Carbon Prepared from Waste of Pineapple Leaf Fiber Production Processing for Removal of Ferric Ion from Aqueous SolutionSumrit Mopoung, Thaksaphon BuntermKMnO4 modified carbon materials from waste of pineapple leaf fiber production processing were prepared and characterized. The effects of % weight of KMnO4 (0-5 %wt) and carbonization temperature (500-700°C) were studied by SEM-EDS, XRD, FTIR and BET. The KMnO4 modified waste carbon was used for Fe3+ removal from aqueous solutions. The effects of KMnO4 modification, contact time, pH and loading … …American Journal of Applied Sciences, Vol. 13, Issue 6 · 25 Jun 2016 · 7,687 accessesView PDFCite
Research ArticleOpen accessIn the abstractEVALUATION OF BIOMASS, INDIAN JUJUBA SEED (IJS) FOR REMOVAL OF CONGO REDL. Sivaramakrishna, M. Sivasankar Reddy, M. Jagadeesh et al.The present investigation deals with the removal of Congo Red (CR) from aqueous solution by using Indian Jujuba Seed (IJS) as low-cost biosorbent. The effect of pH and size experimental parameters has been investigated using a Batch adsorption technique. Adsorption data were modeled using Langmuir and Freundlich adsorption isotherms. Adsorption kinetics was verified by pseudo-first order, pseudo-second order and intraparticle … …American Journal of Environmental Sciences, Vol. 10, Issue 4 · 30 Jun 2014 · 7,181 accessesView PDFCite
Research ArticleOpen accessIn the abstractSYNTHESIS AND CHARACTERIZATIONOF ORGANIC FUNCTIONALIZED MESOPOROUS SILICA AND EVALUATE THEIR ADSORPTIVE BEHAVIOR FOR REMOVAL OF METHYLENE BLUE FROM AQUEOUS SOLUTIONSameer H. Kareem, Inaam H. Ali, M. G. JalhoomThree Mesoporous Silica (MPS) with different functional groups were prepared by one-step synthesis based on the simultaneous hydrolysis and condensation of tetraethoxy silane with organo-silane in the presence of template surfactant Polydimethylsiloxane-Polyethyleneoxide (PDMS-PEO). The prepared materials were characterized by Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA) and nitrogen adsorption-desorption experiments. The results indicate that the preparation of methyl and … …American Journal of Environmental Sciences, Vol. 10, Issue 1 · 28 Feb 2014 · 7,287 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 the Adsorption of the Lead (II) by the Nonliving Biomass Spirogyra neglecta (Hasall) KutzingModher A. Hussain, Aishah Salleh, Pozi MilowProblem statement: Conventional techniques for removing dissolved heavy metals are only practical and cost-effective when applied to high strength wastes with heavy metal ion concentrations greater than 100 ppm. The possibility of using a nonliving algal biomass to solve this problem was carried in this study. Lead (II) was used in this study because it had been reported to cause … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 2 · 30 Jun 2009 · 7,802 accessesView PDFCite
