Background and Objective: Colors can cause major environmental pollutions and are responsible for the carcinogenic and mutagenic risks. In this study, single-walled carbon nanotubes have been carried out to determine the efficiency of removal of Acid Orange 7 ( AO7 ) dye from synthetic textile wastewater. Materials and Methods : In the laboratory study , the color was determined in 484 nm u...
فاضلاب های رنگی صنایع نساجی به ویژه ترکیبات آزو معمولاً حاوی مواد سمی و پایدار در محیط زیست هستند. بنابراین بررسی کارایی روش های متعدد در حذف آن ها ضروری است. ترکیب رنگی acid red 37 از نظر ساختار در گروه رنگ های منو آزو قرار دارد که در حال حاضر در صنایع نساجی کاربرد وسیعی یافته است. هدف از این تحقیق بهینه سازی عوامل مؤثر و مقایسه روش های الکتروفنتون و الکتروکواگولاسیون در حذف acid red 37 است. در...
Due to rapid industrialization and market demand of vibrant textile products, the natural dyes have been replaced by synthetic dyes. These are released in environment with wastewater resulting a major environmental pollution, especially aquatic ecosystem. Hence, organisms like fish highly vulnerable pollution caused wastewater. This study was designed evaluate deleterious effects Basic Red-18 (...
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...
Background and purpose: Textile dye effluents have some potential risks which require effective treatment before discharging into the environment. Advanced oxidation processes can remove pollutants faster than other processes due to active hydroxyl radical production; therefore, increase the efficiency of dye removal. This study was aimed at investigating dye removal process using UVA/ZnO and U...
Dye photodegradation using ozone and Nickel ferrite nanoparticle (NFN) as a photocatalyst was studied. The catalyst was synthesized and characterized by FT-IR, SEM and XRD. Textile dyes including Remazol Red RB (RRRB) and Direct Green B (DGB) were degraded as model compounds. Dye degradation was investigated using UV–Vis and ion chromatography (IC) analyses. The effect of catalyst dosage, pH, s...
