in this study the effects of mesolites from moghueieh region and their particles size on performance, blood biochemical parameters and nutrient digestibility in broiler chickens were evaluated. the experiment was conducted on a completely randomized design with three treatments: without mesolite (control) and with fine particle mesolite (passed of 1 mm sieve and stay in 0.225 mm sieve) or large...

Liquors arising from the dewatering of digested sludge typically contain ammonium levels in the range 200-700mgl(-1) NH(4)(+)-N. These liquors are frequently recycled to the head of the wastewater treatment works (WwTW) untreated and can constitute >25% of the total nitrogen load entering the works at inlet. This paper investigates the use of a clay-based material, MesoLite, as an ion exchange ...

An emerging problem for human health is the exposure to non-regulated mineral fibers with an asbestos-like crystal habit, particularly fibrous zeolites. This study aimed determine if and how selected zeolites (erionite, mesolite, thomsonite) induce toxicity effects on two different in vitro cellular models, adherent murine hippocampal (HT22) immortalized T lymphocyte (Jurkat) cell lines. Before...

Natural mesolite type zeolite was collected, modified by sulfuric acid treatment and characterized by using Powder-X ray diffraction (XRD), Scanning electron microscopy (SEM), Energy dispersive spectroscopy (EDS), Fourier transform infrared spectroscopy (FT-IR).Temperature programmed ammonia desorption (NH3-TPD), Brunauer-Emmer-Teller (BET) surface area analysis.  Modified dealuminat...

S COLECITE (Ca(A12Si3Oa0).3H20) is a naturally occurring zeolite closely related to natrolite and mesolite. Hey and Bannister (I936) examined scolecite in detail and derived from Laue and rotation photographs a nearly orthogonal monoclinic cell with parameters a I8"48 A, b I8"95 A, c 6"54 A,/3 9 ~ 3~'. They noted that scolecite belonged to class m because of its pyroand piezoelectric properties...

amygdaloidal, cavity- and fracture-filling zeolites in eocene volcanic rocks from the kuh-e-aradeh of southern kahrizak, in the northernmost part of central iran have been studied in some detail by optical, chemical analysis, sem, and xrd techniques. the zeolites identified, in order of their relative time of formation from early to late, are tetranatrolite, analcime, natrolite, mesolite, stilb...
