Surface charge density studies as well as characterizations of coagulated dye sludge were investigated to explain the mechanism which takes place during removal of dyes from effluents by chemical coagulation. A simple laboratory model was used to compare two commercially used textile azo dyes: CI “Reactive Black 5” and “Acid Black 1” that were coagulated with synthetic primary coagulants have b...
A screening using several laccase mediators (2,2-azinobis(3ethylbenzthiazoline-6-sulfonic acid (ABTS), 1-hydroxybenzotriazole (HBT), Nhydroxyacetanilide (NHA), 2,2,6,6-tetramethylpiperidin-1-yloxy (TEMPO) and violuric acid (VA)) was performed on the degradation of three reactive textile dyes: Reactive Black 5 (RB5), Reactive Blue 114 (RB114) and Reactive Yellow 15 (RY15). ABTS was the most effe...
Ethanolic Extract of Black Cumin Seed Reduced Radical Reactive from Dimethylbenzanthracene Compounds
Abstract Dimethylbenzantracene is a compound that radical reactive, genotoxic, and immunotoxic. Black cumin seeds have antioxidative properties. The study aimed to determine the effect of black seed ethanolic extract as an antioxidant by observing secretion activity ROI NO peritoneal macrophages in Sprague Dawley (SD) rats induced DMBA. This controlled experiment used 30 male SD rats. test anim...
استفاده از پارچه‌های بافته شده از مخلوط الیاف طبیعی و مصنوعی به منظور بهره‌مند شدن از خواص مطلوب هر یک از اجزاء، متداول می‌باشد. روش شناخته شده برای رنگرزی این نوع کالاها، استفاده از مواد رنگزای راکتیو/ دیسپرس و یا مخلوط آنهاست که برای رنگرزی جزء پنبه‌ای با رنگزای راکتیو از قلیا استفاده می‌شود. از آنجایی که افزودن قلیا سبب بروز مشکلاتی از جمله ایجاد نایکنواختی در رنگرزی شده و از طرفی زمان‌بر اس...
Background and Aim: The development of industry has recently led to the release of 2 × 105 tons of colored wastewater into the environment. The presence of these solutions due to their toxicity and carcinogenic potential can be a threat to human health. The aim of this study was to investigate the efficiency of MWCNTs-CuNiFe2O4 nanocomposite in activating peroxymonosulfate (PMS) for degradatio...
Background and purpose: Some problems such as filtration, centrifugation, and turbidity in effluent has limited the application of activated carbon and many nano-sized adsorbents. The magnetization of adsorbents using magnetic nano-crystals (MNCs) is a useful approach to overcome these problems. In the present study, magnetic activated carbon was synthesized (since it is separated fast and easi...
Brindzová L., Čertík M., Rapta P., Zalibera M., Mikulajová A., Takácsová M. (2008): Antioxidant activity, β-glucan and lipid contents of oat varieties. Czech J. Food Sci., 26: 163–173. The antioxidant activity, total phenolic and β-glucans contents, and the fatty acid profile of total lipids in covered (black and yellow) and naked oats were studied. Oats with black hulls showed a significantly ...
