Background and objective: The wastewater discharged from textile industries is one of the main environmental pollutants that causes many problems for the environment if it is not treated or discharged. The present study compared Fenton oxidation process with coagulation and flocculation using the natural coagulant of Sodium Alginate in order to remove Reactive Red 198 Dye. Materials and method...
Abstract Introduction: Dyes are among the most hazardous chemicals in industrial wastesdue to their toxicity for aquaculture, reduction of light permeability, and in turn development of disorders in photosynthesis process. The current study aimed to investigate the efficiency of coral in removing red reactive 198 from textile dye wastewater was investigated. Materials & Methods: In this e...
Background & Aims of the Study: Azo dyes are used in industrial processes such as textile industry to produce large quantities of colored effluents that contain organic and non-organic materials. So, effective and efficient treatment of them is important for the environmental protection. The aim of this study was to evaluate the efficiency of powder and granular pumice for the ...
The Bombay (Oh) Phenotype is a rare blood group. Phenotypes of this group lack H antigens on their red blood cell membrane and have strongly reactive anti-H in the serum for which patients can receive only autologus or Bombay phenotype red blood cells. We report three cases with Bombay blood group in the city of Yazd to emphasize the transfusion challenges in such patients.
در این تحقیق، ازناسیون فوتوکاتالیزوری دو ماده رنگزای آزوی راکتیو Reactive Red 2 (RR2) و Reactive Red 120 (RR120) در محلول آبی تحت اثر پرتو فرابنفش با استفاده از اکسید روی به عنوان فوتوکاتالیزور مورد مطالعه قرار گرفت. تأثیر عوامل مؤثر بر میزان رنگبری مثل مقدار فوتوکاتالیزور، pH اولیه محلول، غلظت اولیه رنگزا و همچنین اثر نمک‌ها بررسی شد. اسپکتروفوتومتری UV/vis جهت تعیین میزان رنگبری مورد استفاده ...
