Quaternized palm kernel shell was successfully prepared by reacting with N-(3-chloro-2hydroxypropyl)trimethylammonium chloride in basic condition. Adsorption experiments of Reactive Red E (RRE) dye were carried out in single batch system studied at various initial concentration, contact time and pH at 25°C. It was found that at pH 4 quaternized palm kernel shell showed the highest dye removal p...

This study aims to investigate the anaerobic degradation kinetics of reactive dye, C.I. Reactive Red 141 (Evercion Red H-E7B) by partially granulated anaerobic mixed culture using three carbon sources, namely modified starch (MS), polyvinyl alcohol (PVA) and acrylic size (AS) during batch incubation. There is a first-order kinetics reaction in the decolorization processes using MS and PVA as ca...

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 ...

This study investigated the efficiency of electerocoagulation (EC) in removing color from synthetic and simulated textile wastewater. The study on decolorization of mixed dyes is a step toward an effective treatment of textile wastewater. Two representative reactive dye molecules were selected for the synthetic dye wastewater, a blue dye alone and mixed dye (black, blue, red, 1:1:1v/v). The EC ...

Sustainable chemistry is a relatively new field that aims to achieve both economic and environmental goals simultaneously. This paper discusses cleaner more sustainable method for dyeing cotton fabric using Direct Violet 09 Reactive 05 dye. It has been noticed good color characteristics were obtained when was dyed with 35 mL of microwave-treated dye solution 7 pH 2 g Aluminum sulfate 30 min at ...

abstract introduction: dyes are among the most hazardous chemicals in industrial wastesdue 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 experim...

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 (...

In order to improve the color saturation of textile structured chromogenic photonic crystals, this paper proposes that dye adsorbed PSt structural elements (reactive dyes/PSt microspheres) on outer surface can be used construct electrochemically crystals mulberry fabrics by digital printing. method, adsorption conditions and model dyes colloidal microspheres were studied. The structure morpholo...
