The majority of anthraquinone dye released to the environment come from antrapogenic sources. Several techniques are available for dyes' removal. In this study removal of reactive blue 29 (RB29) by an advanced oxidation process sequenced with single wall carbon nanotubes was investigated. Advanced oxidation process was optimized over a period of 60 minutes by changing the ratio of acetic acid t...

This study was aimed to investigate the amount of reactive blue 29 (RB29) dye removal from aqueous solution by Chitosan extracted from Persian Gulf shrimp shell. The effect of parameters such as pH, the concentration of reactive blue 29 dye, contact time, and adsorbent dosage in dye removal was studied. Isotherm, Thermodynamics, and kinetics of adsorption process were also investigated. The...

background: the problem of the environmental pollution by nanoparticles, which have recently entered the cycle of industries process in iran, is very important and can be prevented with applying the proper management approaches. one of the most practical compounds is zno nanoparticle. in the present study  the (lethal concentration-50) lc50 24hr and 48hr of zno nanoparticles exposed-to reactive...

The current commercial application of ink-jet reactive inks to cotton fabrics has been through pre-treating with pad liquor prior to printing. In This study made an effort to provide a single phase ink-jet printing process for printing cotton fabric using the novel cationic reactive dye in ink’s formulation. Cotton fabric was printed upon with the novel cationic reactive dye and commercial anio...

The purpose of this study was to investigate the effect of the structure of reactive dye on cotton ink-jet printing. Cotton fabric was printed upon with three commercial cellulosic reactive dyes which are based on the similar chromophore and possess different numbers of reactive and anionic groups. Colour yield and absorbed dye fixation of the printed cotton were evaluated at various pHs. The i...

Introduction: The dye wastewaters of textile industries are often toxic and persistent in the environment. In previous years, various methods are considerate in the removal of reactive dyes. Reactive red 198 dye is one of the mono azo dyes that is now used in textile industries. The aim of this study was to investigate the efficiency of Russian Knapweed Flower powder in the removal of reactive ...
