We present the first demonstration that the individual 129Xe resonances corresponding to Xen (n = 1-8) clusters inside the alpha-cages of zeolite NaA can be narrowed under magic-angle spinning (MAS). Under these high-resolution conditions we also observe upon addition of Kr the individual peaks corresponding to mixed clusters, XenKrm, inside the alpha-cages, which will allow the first direct de...

Herein, optimization of zeolite NaA/NaX synthesis conditions in order to obtain the final product with high surface area and pore volume was investigated. An optimal condition 5 days aging time crystallization 9 h co-addition cetyltrimethylammonium bromide (CTAB) heptane. All those provided mixed phase between NaA NaX, addition organic phases improved synthesized zeolite. The role CTAB heptane ...

In the article, synthesis of NaA-type zeolite, its processing with alkali and acid, sorption capacity synthesized sorbent (composition: NaA type zeolite:clay=1:1) concerning Fe 3+ , Ni 2+ Cr Cu were studied. The use modified clays leads to significant changes in structural mechanical properties samples. Increasing pH value zeolite-based moulding materials increases proportion plastic deformatio...

Pelletization of zeolitic materials is required to facilitate their practical industrial and commercial applications. Zeolite-NaA was synthesized from fly ash by the fusion method shaped into spherical granules. Bentonite, kaolinite, a combination bentonite with kaolinite were tested as binders different contents 5 10 wt%. The pellet formation optimized. physicochemical properties binders, zeol...

in this scientific research, for the first time, the removal of radioactive strontium-90 (90sr) by γ-mno2-aga zeolite as a novel nanocomposite adsorbent was accomplished under different conditions such as ph, temperature, adsorbent amount and the contact time that are examined from drinking water of ramsar city and monitored via ultra low-level liquid scintillation counting (lsc) technique. pri...
