Introduction: Dyes are among the most hazardous chemicals in industrial wastes due 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 experimental st...
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...
Dye-containing wastewater generated from textile industries is a major source of environmental pollution. Azo dyes, which are the largest group of coloring agents, are widely used in industries.This research investigated the photocatalytic decolorization and degradation of an azo dye Reactive Red 198 (RR198) in aqueous solution with TiO2-P25 (Degussa) as photocatalyst in slurry form using UV li...
Backgrounds and Objectives: Carcinogenic and mutagenic potential of some azo dyes as a category of common dyes in different types of industries has been reported. The degradation of one commercially available dyestuff [C.I. Reactive Red 198 (RR 198)] by means of ultraviolet radiation (UV), ultrasonic irradiation (US), UV/H2O2 and US/H2O2 processes was investigated.Materials and Methods: Photoly...
Background: Dyes have complicated structure, are usually toxic and resistant to biological treatment which entere into environment by industrial waste streams. The aim of this study was the removal of reactive red 198 dye (RR 198) by photolysis (UV) and photocatalytical (TiO2/UVC) processes. This study was conducted to investigate the effects of dye concentration, pH, TiO2 dose, and contact tim...
background and purpose: textile effluents are very difficult to treat satisfactorily due to high variations in their compositions. strong color is one of the main characteristics of textile effluent and, if not eliminated, it can cause serious problems to the environment. in the present study, multi-walled carbon nanotubes (mwcnts) were used as an adsorbent for the removal of reactive red-120 (...
introduction: colored compounds which often are toxic and carcinogen is one of the environmental pollutants. these pollutants should be removed prior than discharge to the environment. the aim of this study was the evaluation of maize tassel powder efficiency for the removal of reactive red 198 dye from synthetic textile wastewater. materials & methods: this experimental study was performed in ...
