Mycotoxins Adsorption by Organomodified Natural Zeolitic Tuff
Zeolites are crystalline hydrated tektoalumosilicates consisting of a three-dimensional framework of SiO4 4and AlO4 5tetrahedra linked through shared oxygen atoms. The heulandite group of zeolites including clinoptilolite are the most abundant zeolites in nature 1, 2 . Clinoptilolite is used in a wide range of industrial and agricultural applications, particularly in animal nutrition. Dietary i...
متن کاملJordanian Zeolitic Tuff as a Raw Material for the Preparation of Substrates Used for Plant Growth
One of the problems faced in front of industry for potting media is limited amount of quality row materials (mainly peat) for unlimited production of quality substrates in the future. The using of natural minerals for production of substrates or as amendments for existing substrates is possible solution for this problem. The natural zeolites with their specific properties – high CEC, high conte...
متن کاملInvestigations of different kinetic models for zinc ions uptake by a natural zeolitic tuff.
The kinetics of uptake of zinc ions from aqueous solutions by natural zeolitic tuff has been investigated. Batch experiments at constant temperature and hydrodynamic conditions have been performed. A decrease in the initial zinc concentration in aqueous solutions prolongs the time needed for equilibrium. Various kinetic models including the film-diffusion model, the surface diffusion model and ...
متن کاملMulti-Scale Analysis of In-plane Behaviour of Tuff Masonry
Various methodologies are available today in engineering professional practice to analyse structures, in particular in the field of masonry structures. Many of the methods are derived from reinforced concrete frames but sometimes they suffer of lack of comprehensive experimental validation due to difficulties to simulate the many different kinds of masonries and they suffer from lack of critica...
متن کاملExceptional chemical and thermal stability of zeolitic imidazolate frameworks.
Twelve zeolitic imidazolate frameworks (ZIFs; termed ZIF-1 to -12) have been synthesized as crystals by copolymerization of either Zn(II) (ZIF-1 to -4, -6 to -8, and -10 to -11) or Co(II) (ZIF-9 and -12) with imidazolate-type links. The ZIF crystal structures are based on the nets of seven distinct aluminosilicate zeolites: tetrahedral Si(Al) and the bridging O are replaced with transition meta...
