Research ArticleOpen accessIn the abstractEquilibrium Kinetics and Isotherm Studies of Cu (II) Adsorption from Waste Water onto Alkali Activated Oil Palm AshZaira Zaman Chowdhury, Sharifuddin Mohd. Zain, Rashid Atta Khan, Abdulbari Abdulrahman AhmedProblem statement: Heavy metal accumulation in waste water could affect aquatic life, human health and overall ecosystem adversely. Therefore, in recent years much emphasis has been given for the use of industrial waste material as low cost adsorbents for removal of metallic contaminants from waste water. Approach: Present study deals with the adsorption equilibrium and kinetics of Cu (II) cation … …American Journal of Applied Sciences, Vol. 8, Issue 3 · 25 Mar 2011 · 7,933 accessesView PDFCite
Research ArticleOpen accessIn the abstractModeling Growth of Microalgae Dunaliella Salina under Different Nutritional ConditionsSergio Santos Jesus, Rubens Maciel FilhoProblem statement: The aim of this study was to find the empirical model that describes the growth kinetics of Dunaliella salina, with low production cost and to estimate parameters of this model. Approach: In this study the strain of D. salina UTEX 200 was cultivated in seawater (0.5 M NaCl) at room temperature with agitation of 150 rpm and luminous … …American Journal of Biochemistry and Biotechnology, Vol. 6, Issue 4 · 31 Dec 2010 · 9,014 accessesView PDFCite

Boughrara, F. AbadProblem statement: The aim of this study is to remove Cd(II) ions from aqueous solutions by adsorption. Mixed sorbent prepared from olive stone and date pit, an agricultural solid by-product was used as adsorbent. Approach: The adsorption experiments of Cd(II) onto the mixture of olive stone and date pit were conducted at different parameters such as, percent of olive stone … …American Journal of Environmental Sciences, Vol. 6, Issue 5 · 31 Oct 2010 · 6,916 accessesView PDFCite
Research ArticleOpen accessIn the abstractThe Removal of Methyl Red from Aqueous Solutions Using Banana Pseudostem FibersMas Rosemal H. Mas Haris, Kathiresan SathasivamProblem statement: The aim of this study was to investigate the removal of methyl red, a mutagenic monoazo dye, from various aqueous solutions using banana pseudostem fibers of the size 212-350 micron. Approach: The parameters studied were the effect of pH, amount of adsorbent, contact time, concentration of adsorbate and agitation speed. Results: Equilibrium data were fitted to the Langmuir … …American Journal of Applied Sciences, Vol. 6, Issue 9 · 30 Sep 2009 · 8,298 accessesView PDFCite
Research ArticleOpen accessIn the abstractHeterogeneous Modeling, Identification and Simulation of Activated Sludge ProcessesIbrahim H. Mustafa, G. Ibrahim, Ali Elkamel, A. H. ElahwanyProblem statement: The activated sludge system is a complex dynamic process and must account for a large number of reactions between large numbers of components. There is necessity for simulation models which describe the dynamic behavior of the activated sludge process. The application of the models in most treatment plants is limited due to lack of appropriate data acquisition and … …American Journal of Environmental Sciences, Vol. 5, Issue 3 · 30 Jun 2009 · 6,592 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption of Methylene Blue from Aqueous Solution onto a Low-Cost Natural Jordanian TripoliAtef S. ALzaydienProblem statement: It is well documented that lead is one of contaminants of industrial wastewaters and its pollution exists in the wastewater of many industries. As a result, recent research has focused on the development of cost effective alternatives using various natural sources and industrial wastes. In this setting, the use of low-cost agricultural materials, waste and residues for recovering … …American Journal of Applied Sciences, Vol. 6, Issue 6 · 30 Jun 2009 · 7,945 accessesView PDFCite

Research ArticleOpen accessIn the abstractDifferent Methods for Pion-nucleus Optical PotentialS. A.E. Khallaf, A. A. IbrahimElastic and inelastic cross-sections for pion scattering on 12C at pion kinetic energy ranging from 50 to 260 MeV are computed using three independent methods of π± -nucleus optical potential, the 3α-particle model of the nucleus, the equivalent local Kisslinger potential and the Laplacian one. Reasonable fits to the measured values are obtained for 12C without adjusting free parameters. The … …American Journal of Applied Sciences, Vol. 2, Issue 5 · 31 May 2005 · 6,387 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordKinetic Study of the Effect of Selected Surfactants on Corrosion of CopperHowaida M. El-KashlanThe rates of copper corrosion were determined by measuring the limiting current of anodic dissolution of copper in phosphoric acid in presence and in absence of cetyl trimethyl ammonium bromide (CTAB) and cetyl pyridinium bromide (CPYB). The rate of corrosion is found to decrease by increasing the concentration of the surfactant. The percentage of inhibition ranged from 1.85 to 33.97% … …American Journal of Applied Sciences, Vol. 5, Issue 4 · 30 Apr 2008 · 7,137 accessesView PDFCite
Research ArticleOpen accessAll words, across the recordKinetic Study of the Effect of Benzoic Acid Derivatives on Copper ElectrodepositionHowaida M. El-KashlanThe effect of anodic oxygen bubbles on the rate of mass transfer in presence of benzoic acid, p-nitro, p-chloro and p-aminobenzoic acids were studied by measuring the limiting current of cathodic deposition of copper from acidified copper sulphate solution using lead anode. It is found that the rate of deposition decreases by adding organic substances. The rate of deposition depends … …American Journal of Applied Sciences, Vol. 5, Issue 3 · 31 Mar 2008 · 7,129 accessesView PDFCite
