ZnO nanoparticles was synthesized by sol gel process and investigated using XRD, FT-IR, SEM and AFM analysis. Advanced oxidation processes (AOP) have showed to be very effective in degradation of most pollutants in wastewaters. The effect of initial concentration for Azure A dye was studied for five concentrations from (1×10 ⁻⁵ M to 5×10 ⁻⁵ M). The...
The newly compounds containing a seven-member ring oxazepane and five-member ring tetrazole derivatives were prepared starting schiffbases. Synthesized by percyclic reactions of imine group with phthalic anhydride resulted the formation of 1,3-oxazepane-4,7dione derivatives (S1, O). The new tetrazole derivatives were obtained from treatment of each...
In this research include synthesis of the new derivative which is a seven-member ring [4-(2-phenyl-2,3-dihydrobenzo-1,3-oxazepine-4,7-dione) benzaldehyde] throughout cycloaddition reaction. Synthesis through the reaction of the schiff base 4-(benzylideneamino)benzaldehyde with phathalic anhydride. This preparing derivative were monitored and charac...
A new azo dye prepared by reaction between 4-aminobenzenesulfonic acid and α-naphthol in several steps. UV spectroscopy was used to determine the maximum wavelength (300 nm) and compare the absorption spectra between primary material and result (new azo dye). Melting point was measured for primary materials and prepared azo dye which was the highes...
In this research include preparation of the new compound which is a seven-member ring 3-amino-2-phenyl-2,3-dihydrobenzo-1,3-oxazepine-4,7-dione through cyclization reaction. Preparation during the reaction of the schiff base benzylidenehydrazine with phathalic anhydride. This compound were characterized by melting points and FT.IR spectroscopy.
A new approach has been demonstrated for the synthesis of solid ammonium sulphate attached to silica rice husk ash. The 3-(aminopropyl)triethoxysilane was immobilized onto silica at room temperature to functionalize the silica with ammine end groups(–NH2). The amine group was sulphated with sulphuric acid to produce a novel micro-rod-like shaped ac...
