Background & Aim: Dyes are one of the most important pollutants of textile industrial wastewater which are toxic, carcinogenic, teratogenic, and non-biodegredable. Basic red is the most commonly used pigment for dying. In this study, peanut shell ash was used as a low cost adsorbent for the removal of basic red 18 from aqueous solutions. Methods: This research was conducted in bench scale in...
Background and purpose: Adsorption processes are widely used in removing pollutants from waste waters, particularly those that are not easily biodegradable such as dyes. In this study natural zeolite, which is easily found in many places, was used as a low-cost adsorbent for removal of dye from effluents. Materials and methods: Adsorption of Azo dyes including two basic and one reactive (React...
This study compares the performance of simulated shallow ponds vegetated with Lemna minor L. under controlled and semi-natural conditions for the treatment of simulated wastewater containing textile dyes. The objectives were to assess the water quality outflow parameters, the potential of L. minor concerning the removal of chemical oxygen demand (COD) and four azo dyes (Acid blue 113, reactive ...
In this study, ZnO nanoparticles were loaded on activated carbon prepared from almond shell (ZnO-NP-AC). Then, this novel material applied as an efficient adsorbent for the ultrasonic assisted simultaneous removal of Basic Blue 41(BB41) and Basic Red 46 (BR46) in binary solution. The efficiency of proposed activated carbon was enhanced by acid treatment and subsequent modification by physical ...

خواص نوری مواد لیفی شکل تابع ظرافت، ضریب شکست و خواص نوری مواد افزودنی می باشد. هدف این تحقیق مطالعه خواص نوری نانو الیاف سفید، رنگی و رنگرزی شده پلی اکریلو نیتریل الکتروریسی شده توسط سه رنگزای بازیک basic red 46، basic g-yellow 28 وbasic blue 41 می باشد. ابتدا نانو الیاف الکتروریسی شده سفید و رنگرزی شده در سه محدوده ی قطری و نانو الیاف رنگی تهیه شد و سپس مورفولوژی و قطر نانو الیاف تهیه شده توس...
Background & Aim: Industrial wastewater is one of the most important sources of hazardous pollutant emissions. Having high levels of various dyes, textile wastewater is considered as one of the major environmental pollutants. The aim of this study was to compare the efficiency of almond shell ash as a natural absorbent in comparison to commercial activated carbon in removing basic red 18 dye fr...
Synthetic dyes are extensively used in many industrial applications like textile, leather and cosmetics. The release of various harmful dyes from these industries into the environment has attracted great attention worldwide in recent years. Biosorption is a very effective dye removal technique from aqueous system. In this research, the biosorption performance of cone of red pine for C.I. Basic ...
