رنگ های نساجی یکی از منابع مهم آلودگی محیط زیست هستند. بیش از 50 درصد رنگ مصرفی، در فرایندهای مختلف رنگرزی وارد فاضلاب شده که علاوه بر تغییر رنگ آب، باعث جلوگیری از نفوذ نور به درون آب و اختلال در عمل فتوسنتز شده که منجر به تخریب اکوسیستم آبی و برخی گونه های آبزیان می شود. در سال های اخیر با تولید و استفاده فراوان رنگ های سنتزی که نسبت به رنگ های طبیعی ساختار پیچیده تری داشته و از نظر شیمیایی ب...
Background & Aims of the Study: Textile wastewaters are very various in chemical qualities. In other words, these industries are one of the largest producing dyes compounds; therefore their treatment is so complex and difficult. The aim of this study was to evaluate the potential removal of Reactive Red 198 and Blue Reactive 19 from synthetic solution by Acaciatortilis shu...

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 ...
plastic mulches have been used in vegetable production in the most parts of the world. in order to evaluate the performance of the colored plastic mulch and different plant density on cucurbita pepo var. rada, an experiment was conducted in agriculture faculty of ferdowsi university of mashhad during the cultural seasons at 2010. the experiment was arranged in factorial experiment based on rand...
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.
The textile dyes are considered as major environmental problems. The dyes can be removed by various methods. Therefore, this study aimed to evaluate the adsorption rate of Reactive Red 198 (RR198) from aqueous solution by activated Azolla filiculoides. This was an empirical-lab study. The Azolla was used as an adsorbent to remove Reactive Red 198 dye. The effect of various parameters was invest...
