Backgrounds and Objectives: Anthraquinone dyes such as reactive blue29 in water resources and industrial wastewater effluents are one of the most environmental setbacks in many countries. Various methods have been considered to remove these dyes One of which is adsorption.Materials and Methods: All adsorption experiments were conducted in different pHs and various concentrations of adsorbents. ...
هدف این تحقیق ارزیابی بازده رنگبری نانوالیاف عامل‌دار شده با سیکلودکسترین (βCD) جهت حذف رنگزای راکتیو از پساب، به روش غوطه‌وری است. نانوالیاف پلی‌اکریلونیتریل(PAN) برای حذف رنگزاهای راکتیو C.I. Reactive Blue 13، C.I. Reactive Blue 21 و C.I. Reactive Red 2 از پساب رنگرزی استفاده و بازده رنگبری برای رنگزاهای فوق به ترتیب 4.7%، 22.5% و 3.4% حاصل شد. سپس نانوالیاف PAN/βCD10 و PAN/βCD50 به ترتیب حا...
background fenton (fe2+ and h2o2) and modified fenton (fe3+ and h2o2) are two popular methods used in advanced oxidation processes (aop) and degradation of persistent organic pollutants (pops), such as dye compounds. in these processes, fe2+ and fe3+ as catalysts and h2o2 as the oxidizing agent are added to the reactor. objectives the aim of the current study is to assess the abovementioned met...
به وسیله ی کربن فعال برپایه پسماند reactive blue 19(rb چکیده- هدف از انجام این پژوهش، تعیین شرایط بهینه حذف رنگ ( انار با استفاده از روش طراحی تاگوچی است. چهار عامل اصلی شامل 9 دقیقه) به عنوان فاکتورهای موثر در راندمان حذف در نظر گرفته شدند که - 500 میلیگرم بر لیتر) و زمان تماس( 1 - اولیه رنگ( 100 غلظت جاذب، غلظت اولیه ،ph برای هر کدام 5 سطح تعیین شد. بر اساس نتایج حاصل از این روش، بیشینه ی با...
Photodynamic therapy (PDT) is a comparatively novel therapeutic method involving a safe light source and a light-sensitive substance, termed as photosensitizers (PSs), such as methylene blue (MB), toluidine blue (TBO), sulfonated aluminum phthalocyanine, chlorine derivatives, nontoxic indocyanine green (ICG), and curcumin (CUR). (1) The combination of a nontoxic PS with low-intensity visible li...
In this work La0.7Sr0.3MnO3 , one group of nanosized perovskite-type oxides were prepared by sol-gel method. The perovskite structure has been characterized by X-ray diffraction (XRD) , scanning electron microscopy (SEM) , energy dispersive X-ray spectrometer (EDX) and Fourier transform infrared (FTIR) . The nanoparticles showed the excellent adsorption properties towards reactive blue 4 (RB4) ...
The open reading frame alr1585 of Anabaena sp. strain PCC 7120 encodes a heme-dependent peroxidase (Anabaena peroxidase [AnaPX]) belonging to the novel DyP-type peroxidase family (EC 1.11.1.X). We cloned and heterologously expressed the active form of the enzyme in Escherichia coli. The purified enzyme was a 53-kDa tetrameric protein with a pI of 3.68, a low pH optima (pH 4.0), and an optimum r...
The P2Y(12) receptor plays a crucial role in platelet aggregation. In the present study, we analyzed the properties of non-nucleotide antagonists at the recombinant human P2Y(12) receptor and searched for amino acids involved in the molecular interaction. Receptor function was assessed by measuring the cAMP response element (CRE)-directed luciferase expression in Chinese hamster ovary cells. Th...
