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 phenol from aqueous solutions by adsorption.
Experiments have been conducted to examine the liquid-phase adsorption of phenol from water by silica gel, HiSiv 3000, activated alumina, activated carbon, Filtrasorb-400, and HiSiv 1000. Experiments were carried out for the analysis of adsorption equilibrium capacities and kinetics. The adsorption isotherm model of the Langmuir-Freundlich type was the best to describe adsorption equilibrium da...

اثر دو نوع حلال CHX (Cyclohexane) و THF (Tetrahydrofuran) برای ارایه کربونیل آهن و همچنین اثر تعداد مکانهای اسیدی در پایه موردنایت (H-Mordenite) به وسیله تغییر نسبت SiO2/Al2O3 برابر 11 و 17 و 61 در ساختار کریستالی موردنایت برای تهیه انواع هیدروکربنها مورد بررسی قرار گرفت. استفاده از حلال CHX می تواند اندازه خوشه های اکسید آهن و یا آهن فلزی کوچکتری را مخصوصاً برای نسبت SiO2/Al2O3 برابر 17 ب...
متن کاملAdsorption Onto Na-Mordenite
In the present study, the adsorption behaviors of mordenite (a common zeolite) with respect to Cu 2+ and Ni 2+ from aqueous solutions were investigated. The sorption data followed the Freundlich and Langmuir isotherms. The maximum sorption capacities were found to be 9.778 and 5.371 mg/g at pH 6, initial concentration of 40 mg/L and temperature of 30 for Cu 2+ and Ni 2+ , respectively. The kine...
