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 abstractAdsorption Study of Electric Arc Furnace Slag for the Removal of Manganese from SolutionC. L. Beh, Luqman Chuah, Thomas S.Y. Choong et al.Problem statement: Steel making slag from Electric Arc Furnace (EAF) is an abundant by-product in Malaysia steel making industry. It has potential to be used for heavy metal removal from contaminated water or waste water. Approach: The aim of this study was to investigate the characteristic and behavior of manganese removal by using EAF slag for efficient metal removal. The … …American Journal of Applied Sciences, Vol. 7, Issue 4 · 30 Apr 2010 · 8,104 accessesView PDFCite
Research ArticleOpen accessIn the abstractRemoval of Cadmium, Copper, Lead and Nickel from Aqueous Solution by White, Yellow and Red United Arab Emirates SandL. Pappalardo, F. Jumean, N. AbdoProblem statement: To remove toxic heavy metal ions from wastewater using local sand as a low cost adsorbent. Approach: Removal efficiency of Cd(II), Cu(II), Pb(II) and Ni(II) from aqueous solution by white, yellow and red UAE sand was investigated at 25.0°C using the methods of batch equilibrium adsorption and column filtration. In each case, a mixture containing 20 ppm of … …American Journal of Environmental Sciences, Vol. 6, Issue 1 · 28 Feb 2010 · 7,600 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdsorption of Pb(II) on Spent Leaves of Green and Black TeaAntonio Zuorro, Roberto LavecchiaProblem statement: In recent years much attention has been focused on the use of biomass residues as low-cost adsorbents for the removal of heavy metal ions from contaminated waters. Spent tea leaves, an abundantly available material that is currently disposed of as a solid waste, are potentially suitable for such applications. Approach: To provide some information on the adsorption properties … …American Journal of Applied Sciences, Vol. 7, Issue 2 · 28 Feb 2010 · 9,588 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
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 abstractUptake and Recovery of Lead by Agarose Gel PolymersAnurag Pandey, Anupam Shukla, Lalitagauri RayProblem statement: The uptake and recovery of lead ions were investigated by using agarose gel polymers. Approach: The experimental results showed that the agarose gel were effective in removing Pb (II) from solution. Biosorption equilibrium was approached within 4 h. Pseudo second-order was applicable to all the sorption data over the entire time range. Results: The sorption data conformed well … …American Journal of Biochemistry and Biotechnology, Vol. 5, Issue 1 · 31 Mar 2009 · 7,629 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential of Agarose for Biosorption of Cu(II) In Aqueous SystemAnurag Pandey, Debabrata Bera, Anupam Shukla, Lalitagauri RayThe ability of agarose gel as an adsorbent for Cu(II) ions in aqueous solution was studied. The experiments were done as batch processes. Batch kinetics and isotherm studies were carried out under varying experimental conditions of contact time, Cu(II) ion concentration, adsorbent dose, temperature and pH. Adsorption equilibrium of agarose gel was reached within 4 h for agarose gel when … …American Journal of Biochemistry and Biotechnology, Vol. 3, Issue 2 · 30 Jun 2007 · 6,829 accessesView PDFCite

Research ArticleOpen accessAll words, across the recordPhytoremediation and Adsorption of Heavy Industry Emitted from Cement Industry through Plant Leaves, Case Study: Golestan Peivand Cement FactorySoleyman Ghorbanzadeh, Meysam Madadi, Sara Abdollahi, Kaveh Ostad-Ali-AskariCement factories are found to be one of the major causes of pollution. Cement mist and dusts depositions affect the photosynthesis, secretion and fertility of the plant. Increasing the concentration of airborne dust reduces photosynthetic potential in leaves, closes leaf stomatals and, in general, reduces the growth and fertility of plants. The purpose of this study is to determine the … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 4 · 23 Nov 2020 · 6,438 accessesView PDFCite
