Removal of Heavy Metals from Aqueous Solution by Mordenite Nanocrystals
This study examined the ability of the synthetic mordenite nanocrystal to remove Tl(III) and As(III) from an aqueous solution. The determination of the concentration changes of H+ and OH- quantities in the acidic (pH 3) and alkali (pH 9) treated mordenite nanocrystals were done by the potentiometric titration curves. The maximum uptake capacities (Qmax) of these metal ions using the mordenite i...
متن کاملRemoval of heavy metals from aqueous solution by sawdust adsorption.
The adsorption of lead, cadmium and nicel from aqueous solution by sawdust of walnut was investigated. The effect of contact time, initial metal ion concentration and temperature on metal ions removal has been studied. The equilibrium time was found to be of the order of 60 min. Kinetics fit pseudo first-order, second-order and intraparticle diffusion models, hence adsorption rate constants wer...
