-The use of powdered activated carbon treatment (PACT), based on simultaneous adsorption and biodegradation, is effective for treating organic toxic pollutants, present in industrial wastewaters. Removal of phenol and aniline from aqueous solutions by biological treatment alone, by adsorption on powdered activated carbon (PAC) alone and by simultaneous adsorption and biodegradation were compare...
A bacterial strain Pseudomonas sp. a3 capable of degrading nitrobenzene, phenol, aniline, and other aromatics was isolated and characterized. When nitrobenzene was degraded, the release of NH(4) (+) was detected, but not of NO(2) (-). This result implied that nitrobenzene might have a partial reductive metabolic pathway in strain a3. However, aniline appeared as one of the metabolites during th...
Background and aims : Aniline as one of the aromatic amines is a widely distributed environmental pollutant resulting from the manufacture of dye materials and agricultural chemicals such as herbicides. It is frequently used by the industry such as the raw material in the manufacture of dyes, rubbers, pharmaceutical preparation, plastic and paint. It is also a common by product from paper and...
Two generations of nitrobenzhydrol-based photocages for Zn(2+) have been prepared and characterized. The first series includes the tridentate ZinCast-1 utilizes a bis-pyridin-2-ylmethyl-aniline ligand that forms a 5,5-chelate ring upon metal binding. The related photocages ZinCast-2 with a N-[2-(pyridine-2-yl)ethyl]-N-(pyridine-2-ylmethyl)aniline (5,6-chelate ring) and ZinCast-3 with a N,N-bis[...
Mutagenic/carcinogenic 9-(4'-aminophenyl)-9H-pyrido[3,4-b]indole [aminophenylnorharman (APNH)] is formed from norharman and aniline in the presence of cytochrome P450 3A4/1A2. Because both precursors are widely distributed in the environment, human exposure is unavoidable. To clarify APNH formation in the human body, amounts of the compound in 24-h human urine collected from smokers and nonsmok...
Electrochemical polymerization of aniline is one of the most promising methods to prepare polyaniline (PANI) materials. However, during this process, the electrolyte solution must be replaced after electropolymerization of a certain time because of the generation and the accumulation of the by-products, which have significant effects on the morphology, purity and properties of PANI products. Tr...
Size effects during phase transformations change the composition of coexisting phases in ternary mixtures. The consequence is a distribution coefficients components, which interest for microextraction. concentration dependence degree extraction separable mixtures (aniline-methylcyclopentane-hexane and water-phenol-toluene) submicron drops was simulated by methods equilibrium chemical thermodyna...
A model aquatic ecosystem is devised for studying relatively volatile organic compounds and simulating direct discharge of chemical wastes into aquatic ecosystems. Six simple benzene derivatives (aniline, anisole, benzoic acid, chlorobenzene, nitrobenzene, and phthalic anhydride) and other important specialty chemicals: hexachlorobenzene, pentachlorophenol, 2,6-diethylaniline, and 3,5,6-trichlo...
We report the synthesis of halido Os(II) p-cymene complexes bearing bidentate chelating phenylazobenzothiazole (AZBTZ) ligands. Unlike the analogous phenylazopyridine (AZPY) complexes, AZBTZ-NMe2 is capable of both N,N-coordination to Os(II) and cyclometalation to form N,C-coordinated species. N,C-Coordination occurs via an azo nitrogen and an ortho carbon on the aniline ring, as identified by ...
در این کار پژوهشی، گرافیت اکسید و گرافن با روش اصلاح شده هامرز سنتز شده است. همچنین نانوکامپوزیت های گرافیت اکسید/ پلی آنیلین و گرافن/ پلی آنیلین را با مورفولوژی های کنترل شده از قبیل نانو فایبر، نانو کره، نانو لوله، نانو ریبون، نانو گرانول و نانو میله از طریق پلیمریزاسیون درجای مونومر آنیلین در حضور گرافیت اکسید تهیه شده و سپس کامپوزیت گرافیت اکسید/پلی آنیلین با استفاده از هیدرازین کاهش داده و...
