Kinetic study of heavy metal ions removal from aqueous solutions using activated pumice stone
Background: The presence of heavy metals in aquatic and terrestrial ecosystems causes harmful effects to living organisms in the environment. This research aimed to determine the potential of activated pumice stone (APS) as a sorbent for the removal of Cd, Cu, and Zn from wastewater. Methods: This research was conducted during 2013 on a laboratory scale. The study was performed using batch exp...

متن کاملPreliminary Adsorption study for Heavy Metal Removal with Ion-Exchange Resins in the Teaching Laboratory
This paper reports on the adsorption of Cr(VI), Cu(II) and Pb(II) from laboratory solution by the use of Chelex 100 (C100) and Amberlite IRA400 ion exchange resins. Metal loading at initial pHs of 3 to 8 at 1-100 mg/L were studied based on Q max and K f values of the Langmuir and Freundlich isotherm models, respectively. Lead was sorbed the most (Q max = 75.19 mg/g, at pH 6), followed by Cu (Q ...
متن کاملHighly efficient catalyst for removal of heavy metal ions modified by a novel Schiff base ligand
An alomina-based nano adsorbent was prepared by modification of the external surface of γ-alumina (γ-Al2O3) nanoparticles with functional groups of a new Schiff base 4-[(2-hydroxy-3-methoxy-benzylidene)-amino]-5-methyl-2,4-dihydro-[1,2.4]triazole-3-thione] “L”. In order to the removal of Cr(VI) from aqueous solutions, we used the reaction of the sodium dodecyl sulfate coated nano-alumina with L...
