Research ArticleOpen accessIn the abstractRemoval of Pb+2 Ions from Aqueous Solutions by Adsorption on Kaolinite ClayWaid Omar, Hossam Al-ItawiThe adsorption potential of the kaolinite clay for the removal of lead ions from aqueous solutions was tested. The measured adsorption isotherms at the different temperatures 298.15 K, 308.15 K and 318.15 K were found to be perfectly fit to the Langmuir isotherm equation. A high adsorption capacity was calculated. An increase in the retention capacity with increasing temperature was … …American Journal of Applied Sciences, Vol. 4, Issue 7 · 31 Jul 2007 · 7,792 accessesView PDFCite
Research ArticleOpen accessIn the abstractPotential of Rice Husk and Rice Husk Ash for Phenol Removal in Aqueous SystemsA. H. Mahvi, A. Maleki, A. EslamiThe potential of rice husk and rice husk ash for phenol adsorption from aqueous solution was studied. Batch kinetics and isotherm studies were carried out under varying experimental conditions of contact time, phenol concentration, adsorbent dose and pH. Adsorption equilibrium of rice husk and rice husk ash was reached within 6 hours for phenolic concentration 150-500 μg/L and 3 hours … …American Journal of Applied Sciences, Vol. 1, Issue 4 · 31 Dec 2004 · 10,171 accessesView PDFCite
Research ArticleOpen accessIn the abstractMNM1D: A Numerical Code for Colloid Transport in Porous Media: Implementation and ValidationTiziana Tosco, Rajandrea SethiProblem statement: Understanding the mechanisms that control the transport and fate of colloidal particles in subsurface environments is a crucial issue faced by several researchers in the last years. In many cases, natural colloids have been shown to play a major role in the spreading of strongly sorbing contaminants, while manufactured micro-and nanoparticles, which are nowadays widely spread in the … …American Journal of Environmental Sciences, Vol. 5, Issue 4 · 31 Aug 2009 · 8,291 accessesView PDFCite
