مقدمه: صنایع نساجی و رنگرزی یکی از مهمترین صنایع هر کشوری محسوب میگردند. در این گونه صنایع به دلیل استفاده از انواع رنگها در فرآیندهای مختلف، فاضلاب حاصل نیز به شدت رنگی بوده و میبایست قبل از تخلیه به محیطزیست تصفیه گردد. لذا هدف از این تحقیق بررسی کارایی نانوذرات آلومینا در حذف رنگ Acid Red 18 از محیطهای آبی است. روش بررسی: این تحقیق در مقیاس آزمایشگاهی انجام شد. در این آزمایش یک محلول سن...
in this paper cufe2o4, nanocrystalline powders were prepared. also, the supported cu ferrite was obtained by impregnation of the supports with cu and fe nitrates solutions, for calcination temperature 450 ºc. the samples were characterized by x-ray powder diffraction (xrd) and fourier transform-infrared spectroscopy (ft-ir). photocatalytic degradation of acid red 206 in water was studied. cufe2...
The photocatalytic degradation of Acid Red 91 (AR91) and Acid Yellow 23 (AY23) with different molecular structures and different substitute groups using Pt modified TiO2 (PtTiO2 ) nanoparticles was investigated in the presence of visible light irradiation. Pt-TiO2 nanoparticles were prepared with photodiposition method (PD) and characterized by X-ray diffraction (XRD), scanning electron microgr...
Background: Apple is the most consumed fruit in many countries of the world and has very important role in individual's diet and health. The aim of this study was to determine the vitamin C (Ascorbic acid), organic acids (citric acid and malic acid), and phenolic compounds concentrations of apple cultivars grown in Khorramabad and Boroujerd cities. Materials and Methods: At this cross-sectiona...
Yellow rust (caused by Puccinia striiformis f. sp. tritici) is an important fungal disease affecting wheat production and quality. The purpose of this study was to identify the spectral band regions that influence how changes throughout year determining plant responds yellow when it applied test materials at various doses (0%, 25%, 50%, 100%). Eser, Bayraktar 2000 Demir varieties showed high co...
Introduction: In order to improve caries detection, invasive methods should not be used and caries detector is useful, and antibacterial solutions can be used as well as a biological method for caries detection. Aim of the present study was to differentiate sound dentin from infectious dentin by two coloring solutions: acid red and povidone iodine. Methods: In this experimental investigation,...
The discovery of biomarkers of intake in nutritional epidemiological studies is essential in establishing an association between dietary intake (considering their bioavailability) and diet-related risk factors for diseases. The aim is to study urine and plasma phenolic and microbial profile by targeted metabolomics approach in a wine intervention clinical trial for discovering and evaluating fo...
Red mud is a hazardous waste of the alumina industry that contains high amounts iron, aluminum, titanium and rare-earth elements (REEs). One promising methods for extraction iron from red carbothermic reduction with addition sodium salts. This research focuses on process hydrochloric high-pressure acid leaching using 10 to 20% HCl two samples non-magnetic tailings obtained by 60 min roasting at...
A selective electrochemical method for the determination of uric acid was developed by using nano poly cresol red modified glassy carbon electrode. This new material has been characterized by Scanning Electron Microscopy, cyclic voltammetry and Differential pulse voltammetry. This modified electrode shows excellent electrocatalytic activity towards the oxidation of uric acid in the presence of ...
