Liquid Crystalline of Alumina : Grafted with Acrylic Acid and Organic Monomers and its Adsorption Properties
ISBN: 9783639365757 / Angielski / Miękka / 2011 / 128 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych (Dostawa w 2026 r.) In this work commercial ceramic material aluminum oxide (alumina, Al2O3) was grafted and extended by three different monomers using free radical polymerization. These monomers are acrylic acid, 4-(4'-butoxy- and 4'-octoxybenzylideneamino) phenylmthacrylate to produce three polymers; polymer A, polymer B and polymer C. The last two polymers showed liquid crystalline properties. The ability of these three alumina-grafted polymers was examined for adsorption of phenol and p-chlorophenol under different conditions i.e., initial concentrations, pH and temperatures.

Removing of Some Organic and Inorganic Pollutants
ISBN: 9783843363297 / Angielski / Miękka / 2010 / 212 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych (Dostawa w 2026 r.) The use of Iraqi Clay Minerals (ICM) for the removal of hazardous organic and inorganic water pollutants is investigated using synthetic aqueous solutions. Four locally available clays namely, bentonite, kaolinite, porcelainite and diatomite, were purified, sampled and characterized by XRD, XRF, FTIR spectroscopy and SEM. The surface areas were determined using BET and methylene blue adsorption method. Cation exchange capacity (CEC) was estimated using the method of adsorbing an ethylenediamine complex of copper method and the modifier loading was calculated from the total carbon analysis....

Durability Study of High Impact Polystyrene
ISBN: 9783845476513 / Angielski / Miękka / 68 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych (Dostawa w 2026 r.) The durability of high impact polystyrene (HIPS) as food packaging of dairy products was studied. Samples cut from container made from HIPS were exposed to different weathering conditions for 25, 50, 75 and 100 hours and with two stages tests before and after being used in food packaging using artificial aging in Xenontest-150 device. Three mechanical properties, tensile strength, elongation at break and impact strength were measured before and after the exposure to UV radiation. In general all mechanical properties decrease with time of exposure to UV light. Embrittlement of HIPS with...

Removal of Nitrophenols by Modified Attapulgite
ISBN: 9783659235061 / Angielski / Miękka / 2012 / 116 str. Termin realizacji zamówienia: ok. 10-14 dni roboczych (Dostawa w 2026 r.) This thesis concerns with the use of Iraqi Clay (attapulgite) for the removal of hazardous organic water pollutants, namely o-nitrophenol, m-nitrophenol and p-nitrophenol from their aqueous solutions. Attapulgite was modified by surfactant (hexadecyltrimethylammonium bromide (HDTMA)). Attapulgite and its modified form (A-HDTMA), were purified, sampled and characterized by X-ray diffraction (XRD), FTIR spectroscopy, scanning electron microscope (SEM) and energy dispersive X-ray spectroscopy (EDS) technique. Batch experiments were carried out at pre determined equilibration time, solution pH,...
