چکیده
In this study, microcrystalline cellulose (MCC) was modified to oxidized (OC), 6-deoxycellulose hydrazide and (N,N-diethyl)amine (MCC-Hyd MCC-DEM) derivatives employed as supporting material for the synthesis of copper nanoparticles (NPs). Copper ions from aqueous solution were adsorbed then reduced zero valent (ZVC) NPs using sodium borohydride on films prepared derivatives. The characterization Cu embedded performed Fourier Transform Infrared Spectroscopy, Elemental analysis, X-ray diffraction, Scanning Electron Microscopy, photoelectron spectroscopy Nuclear Magnetic Resonance spectroscopy. Ultraviolet/Visible (UV–VIS) degradation studies 4-nitrophenol (4-NP) various azo dyes viz. Congo Red, Methylene Blue, Methyl orange. Results revealed that all showed only in presence ZVC NPs. Oxidized cellulose, MCC-Hyd MCC-DEM excellent efficiencies (> 85%) cases. Our findings MCC could be efficient renewable candidates removal water pollutants future.Graphical abstract

Degradation and removal of organic pollutants by BaFe2O4 nanostructures, synthesis and characterization
BaFe2O4 nanostructures have been synthesized through a simple sonochemical reduction approach. X-ray diffraction characterization suggested that the product consists of cubic phase pure BaFe2O4. The as-prepared products were also characterized by scanning electron microscopy (SEM) and transmission electron microscopy (TEM). An X-ray energy dispersive spectroscopy (EDX) study further confirmed t...

متن کاملsynthesis and characterization of some macrocyclic schiff bases
ماکروسیکلهای شیف باز از اهمیت زیادی در شیمی آلی و دارویی برخوردار می باشند. این ماکروسیکلها با دارابودن گروه های مناسب در مکانهای مناسب می توانند فلزاتی مثل مس، نیکل و ... را در حفره های خود به دام انداخته، کمپلکسهای پایدار تولید نمایند. در این پایان نامه ابتدا یک دی آلدئید آروماتیک از گلیسیرین تهیه می شود و در مرحله بعدی واکنش با دی آمینهای آروماتیک و یا آلیفاتیک در رقتهای بسیار زیاد منجر به ت...
15 صفحه اولSynthesis and characterization of novel silyl derivatives of curcumin
Abstract:Turmeric is a member of the ginger family (Zingiberaceae), which is extensively used as a spice, food preservative and colouring material. Curcumin is a main bioactive natural compound derived from the rhizome of this plant. Curcumin can exist in several tautomeric forms, keto and enol. The keto form is more stable than enol form. Silyl ethers have proven to be versatile substrates for...
