Red clay contains solid aluminosilicate has been shown to be reactive in the presence of an alkaline activator. The addition coal fly ash and lime improvements their mechanical physical properties geopolymer products. FTIR analysis SEM images product have formation gel geopolymeric product. maximum compressive strength products GP-RFL was achieved 15.92 N/mm2 having water absorption 10.47 % bul...
Background and Objective: The most used dyes in textile industries are Azo Group dyes. Azo dyes have complex aromatic compounds, low chemical and biodegradable stability. Due to these properties, treatment of this type of wastewater by conventional methods will not meet environmental standards. The advanced oxidation process has been widely used to treat organic matter from wastewater. In this ...
در این تحقیق روش طیف سنجی جذبی پسابهای رنگرزی مورد استفاده قرار گرفته است و پس از تایید پیروی محلول رنگزاهای cibacron red 3b-a (مونوکلروتریآزینیلی) و remazol red 3b (وینیل سولفونی) از قانون بیر-لامبرت، و سنجش تاثیر عوامل مختلف بر روی طیف جذبی محلول این رنگزاها، راندمان تثبیت رنگرزیهای انجام گرفته با استفاده از این دو رنگزا، در عمقها و شرایط مختلف رنگرزی به کمک طیف سنجی جذبی محلولهای رنگرزی، شست...
The purpose of this study was to assess red beet as a natural colorant in emulsified pork sausage and to investigate the effect of red beet on quality characteristics of emulsified pork sausage during 20 d of cold storage. Red beet was prepared as a powder and a substitute with sodium nitrite at 0.5% and 1.0% levels in emulsified pork sausage. Red beet significantly increased the moisture conte...
Introduction Routine antenatal serological screening has been practised throughout the United Kingdom and worldwide for about 30 years.' Originally introduced to detect pregnancies at risk of haemolytic disease of the newborn (HDN) due to Rh anti-D antibodies, its continued use has led to an increasing realisation of the clinical importance of other red cell antibodies in the pathogenesis of HD...
Irradiated red ginseng powder (2.4 kg) in commercial bottles was transported from Korea to Iowa State University (USA) via air(10 days) and sea-cargos (50 days) to prove its qualities and identity. The microbial loads of transported samples by both methods after 5 kGy irradiation were reduced from 10 to 10CFU/g in total aerobic bacteria and from 20CFU/g (minimum detection level) to negative in ...
Removal of brilliant red (C. I. Reactive Red 2) from aqueous solutions by adsorption on fish scales of Labeo rohita was investigated. Batch adsorption experiments were carried out under different experimental conditions such as contact time, initial concentration of dye solutions, temperature and pH of the solution. The optimum pH for the adsorption experiment was found to be 7.2. The equilibri...
Background and purpose: Dyes are one of the major sources of chemicals responsible for environmental pollution. Synthetic dyes degradation in industrial wastewaters has received increasing attention due to their high solubility and stability in water. In the present study, the photocatalytic efficiency of as-synthesized nano- TiO2 supported on the H-form Fe- Fe-ZSM-5 zeolite was investigate...
Abstract Background: Wastewater from factories and manufacturing centers because of various compounds, complicates the process of wastewater treatment. Among this industries, the textile, paper pulp, food, pharmacy and leather industry due to consumption of various types of chemicals are the most important importers of color pollutants to environment, which have harmful effects...
