Zeolite – sepiolite nanoheterostructures
Zeolite–sepiolite inorganic nanoheterostructures have been hydrothermally synthesized by adding a dispersion of colloidal sepiolite to a solution able to produce a nanocrystalline zeolite (silicalite). The obtained product could be recovered in good yield by simple filtration only when the relative sepiolite concentration exceeded a threshold of 1.8 wt% in the synthesis mixture (amounting to 1:...
متن کاملSolid-state Nuclear Magnetic Resonance Study of Sepiolite and Partially Dehydrated Sepiolite
The assignment of the Si CP/MAS-NMR spectrum of naturally-occurring sepiolite clay was re-examined using Si COSY and H-Si HETCOR pulse sequences. Each of the three main resonances at 92.1, 94.6 and 98.4 ppm has been attributed to one of the three pairs of equivalent Si nuclei in the basal plane, and the resonance at 85 ppm to Q(Si-OH) Si nuclei. On the basis of the COSY experiment, the resonanc...
متن کاملkinetics and thermodynamics of lead adsorption from aqueous solutions onto iranian sepiolite and zeolite
a good understanding of adsorption equilibrium and thermodynamics is required to design and operate an adsorption process. this study was conducted to assess the adsorption percentage of pb2+ ions as a function of contact time, solution ph and temperatures, and adsorbent dosage through a series of batch experiments. the methods including zeta potentials, specific surface area measurements and t...
متن کاملOrganophilic Tendencies of Two Transplantable Tumors of the Mouse*t
Relationships between the transplanted tumor and its host . --A growing neoplasm that will eventually cause the death of the hos t may or may not develop daughter colonies, or metastases. When a mouse tumor is successfully transplanted into new hosts the same tendency either to metastasize in a certain percentage of the host mice or to remain localized is apparently shown by the tumors of later...
متن کاملA study of Spanish sepiolite workers.
BACKGROUND Sepiolite is an absorbent clay that is used as pet litter. It forms thin crystals, which are a transition between chain and layered silicates. Inhalation studies in animals have shown no evidence of pulmonary damage. This paper reports a cross sectional study of the total work force of the largest sepiolite production plant in the world. METHODS Two hundred and eighteen workers (21...
