در این تحقیق اطلاعاتی در مورد کاربرد فرآیند فنتون به عنوان یک روش اکسیداسیون پیشرفته برای تصفیه پساب حاوی یک رنگزای آزو راکتیو (Reactive Red 120) گزارش شده است. برای به دست آوردن شرایط عملکرد مقرون به صرفه برای کاربرد فرآیند اکسیداسیون فنتون، تأثیر پارامترهای اصلی عملیات مثل میزان سولفات آهن، آب اکسیژنه، pH محلول، دما، غلظت اولیه رنگزا و حضور غلظت‌های متفاوت از کلرید سدیم و سولفات سدیم در مقیاس...

Azo dyes are widely used in textile industries. Removal of the color from textile waste water is a striking issue. To curb this issue, biological treatment can be employed rather than physicochemical processes. In this work, Bacillus subtilis is used to degrade the reactive dye – RED M5B. It is found that decolorization was due the action of enzyme peroxidase produced by the organisms during it...

Stepwise one-electron reduction of oxygen to water produces reactive oxygen species (ROS) that are chemically and biochemically similar to reactive sulfide species (RSS) derived from one-electron oxidations of hydrogen sulfide to elemental sulfur. Both ROS and RSS are endogenously generated and signal via protein thiols. Given the similarities between ROS and RSS, we wondered whether extant met...

The effect of oxidative stress on human red blood cell AMP-deaminase activity was studied by incubating either fresh erythrocytes or hemolysates with H(2)O(2) (0.5, 1, 2, 4, 6, 8, and 10 mm) or NaNO(2) (1, 5, 10, 20, and 50 mm), for 15 min at 37 degrees C. AMP-deaminase tremendously increased by increasing H(2)O(2) or NaNO(2) at up to 4 and 20 mm, respectively (maximal effect for both oxidants ...

Article history: Received 22 April 2016 Received in revised form 7 September 2016 Accepted 3 October 2016 In this work, response surface methodology (RSM) and artificial neural network (ANN) were used to predict the decolorization efficiency of Reactive Red 33 (RR 33) by applying the O3/UV process in a bubble column reactor. The effects of four independent variables including time (20-60 min), ...

The oxygen-labile, activating enzyme for iron protein from the photosynthetic bacterium, Rhodospirillum rubrum, was purified 11,800-fold using a combination of chromatophore washing, DE52-cellulose chromatography, hydroxylapatite chromatography, reactive red-120 cross-linked agarose chromatography, reactive red-120 cross-linked agarose chromatography, and Sephadex G-75 gel filtration. Activatin...

Objective(s): Peripheral giant cell granuloma (PGCG) is a reactive, proliferative, exophytic lesion developing on the gingiva and alveolar ridge, originating from the periosteum or periodontal membrane. The lesion develops mostly in adults, commonly in the lower jaw, with slight female predilection although is uncommon in children. Cases Report: Two boys, 11 and 8-years-old respectively, otherw...
