A goal of our study was to find an alternative to nano-silver-based antimicrobial materials which would contain active silver immobilized in a solid matrix that prevents its migration into the surrounding environment. In this study, we investigated whether silver cations dispersed in an atomic form and trapped in an ion-exchanged zeolite show comparable antimicrobial activity to silver nanopart...
aluminophosphate-5 (alpo4-5) nano-pore zeolite was synthesized. the effect of alteration in precursor gel preparation on the morphology of zeolite was studied. the effect of variety of synthesis conditions on the purity, crystal and pore size, and crystallinity of alpo4-5 zeolite been studied. a hydrothermal synthesis has been used to produce nano-pore aluminophosphate-5 crystals. the crystals ...
Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Background and Objectives:Benzene, toluene and Xylenes (BTX) are organic pollutants, which are mainly associated with oil and its derivatives. BTX is environmental contaminants and considered harmful to human heal...
Synthesis of zeolite Y membranes from submicrometer (>100 nm) and nano seed (<100 nm) crystals on alumina supports was examined and the separation characteristics of these membranes for CO(2) and N(2) were studied. Two secondary growth solutions were examined, one for a rapid growth (hours) and one for a slower growth process (days). Membranes formed from the rapid growth solution resulted in 2...
Today, sulfur removal from fuels has improved by new adsorbents such as zeolites that needs extensive studies. This study investigates the feasibility of sulfur compounds adsorption on improved nano zeolite existing in organic fuels and desorption of them from nano-adsorbent.Some properties of improved nano zeolite were analyzed to receive better sulfur compounds adsorption.<e...
objective(s): binary hybrids of chitosan-zeolite have many interesting applications in separation and bacteriostatic activity. materials and methods: template free zsm-5 zeolite was synthesized by hydrothermal method, physical hydrogels of nano chitosan in the colloidal domain were obtained in the absence of toxic organic solvent and then nano chitosan/zsm-5 hybrid composites with nano chitosan...
در این مقاله، زئولیت NaYبه روش سل-ژل و بدون حضور الگوهای آلی و افزودنیها سنتز شد. سپس با استفاده از روش تبادل یونی به زئولیتAgY تبدیل شد. در مرحله بعدی، نانوذرات منگنز دی اکسید در منافذ زئولیت AgY به روش فضای محدود(CS) سنتز شدند. کامپوزیت nano-MnO2/Zeolite AgY به روشهای SEM، XRD، IR و AAS مورد شناسایی قرار گرفت. رفع و دفع آلودگی 2-کلرو اتیل فنیل سولفید (شبه عامل خردلی) و دیمتیل متیلفسفو...
In order to investigate the gas separation ability of a column packed with nanozeolitic material, nano NaY zeolite was synthesized and granulated. These uniform granules packed in a chromatographic column were utilized for separation of Xe and Kr under various operating conditions. With regards to the response peaks obtained from trace injections of Xe and Kr into the column, the first and seco...
