| 1 | Influence of Nitric Acid Concentration on Characteristics of Olive Stone Based Activated Carbon显示文摘In this work we investigated the effect of nitric acid concentration on the pore structure,surface chemistry and liquid phase adsorption of olive stone based activated carbon prepared by mixing process using phosphoric acid and steam as activating agents.Chemicals and textural characterization show that the increase of HNO3concentration increases considerably the total acidic groups but decreases specific surface area and pore volume.The study of adsorption in aqueous solutions of two organics,phenol and methylene blue,on raw and oxidized activated carbon indicates that the treatment of mixed activated carbon with different concentrations of nitric acid improves the adsorbent capacity for methylene blue at HNO3concentrations less or equal to 2 mol·L 1,while it has a negative effect on phenol adsorption. | Nouha Soudani Souad Souissi-najar Abdelmottaleb Ouederni | 2013 | Chinese Journal of Chemical Engineering2013，21，12： | 6 |
| 2 | Adsorption of dyes onto activated carbon prepared from olive stones显示文摘Activated carbon was produced from olive stones(OSAC) by a physical process in two steps. The adsorption character of this activated carbon was tested on three colour dyes molecules in aqueous solution: Methylene blue(MB), Rhodamine B(RB) and Congo Red(CR). The adsorption equilibrium was studied through isotherms construction at 30℃, which were well described by Langmuir model. The adsorption capacity on the OSAC was estimated to be 303 mg/g, 217 mg/g and 167 mg/g respectively for MB, RB and CR. This activated carbon has a similar adsorption properties to that of commercial ones and show the same adsorption performances. The adsorption kinetics of the MB molecule in aqueous solution at different initial concentrations by OSAC was also studied. Kinetic experiments were well fitted by a simple intra-particle diffusion model. The measured kinetics constant was influenced by the initial concentration and we found the following correlation: K id1.55C0 0.51. | Souad NAJAR-SOUISSI Abdelmottaleb OUEDERNI Abdelhamid RATEL | 2005 | Journal of Environmental Sciences2005，17，6： | 2 |

| 6 | Adsorption of rare earth elements onto diatomite M45:Experimental investigations and modeling with statistical physics theory显示文摘The separation of rare earth elements using diatomite M45 from aqueous solutions was studied.The experimental isotherms for the adsorption of trivalent lanthanum,cerium,and neodymium cations on this adsorbent were quantified under strongly acidic conditions(pH 2)at 298-328 K.The adsorption equilibria of these earth elements were analyzed using two statistical physics models(homogeneous and heterogeneous monolayer models).The results show that the adsorption of these ions implies a multiionic mechanism,which is exothermic.Si-containing functional groups are responsible for the adsorption of these rare-earth elements on the diatomite surface.A heterogeneous statistical physics model confirms that two Si-based functional groups participate in the separation of these cations.The calculated adsorption capacities at saturation follow the order:neodymium>cerium>lanthanum.Calculated interaction energies range from 28600 to 40100 J/mol,indicating physical adsorption on diatomite M45.This study demonstrates that diatomite M45 is a promising separation medium that can be used for the recovery of REEs dissolved in aqueous solutions via adsorption. | Fatma Dhaouadi Guilherme L.Dotto Julien Vieillard Diana Pinto Luis F.O.Silva Éder C.Lima Mu Naushad Fatma Aouaini Samia Nasr Adrián Bonilla-Petriciolet Abdelmottaleb Ben Lamine | 2023 | Journal of Rare Earths2023，41，11： | 0 |
