Title
Synthesis of Mesoporous Zeolite Y and Its Application for Adsorptive Removal of Heavy Metals (Mn2+, Fe2+)
박서현 Seo-hyun Pak , 박찬규 Chan-gyu Park
Abstract
We studied a simple approach for synthesis of mesoporous Y(M-Y) from commercial zeolite Y precursors by treating of NaOH with CH3(CH2)15N(Br)(CH3)3 as template. The physicochemical properties of the mesoporous zeolites Y were then analyzed using XRD, nitrogen full-isotherms at 77 K, SEM and TEM. The nitrogen adsorption-desorption analysis showed that surface area and pore diameter of synthesized mesoporous zeolite Y(M-Y) were 1072 ㎡/g and ~3.3 nm, respectively. And M-Y was applied for the removal of Mn2+ and Fe2+ from aqueous solution. This material, which introduces mesoporosity with zeolite Y character, displayed a superior adsorption capacity than commercial zeolite Y when used as an adsorbent for the removal of Mn2+ and Fe2+.
