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 ...
Background and purpose: Chemical dyes are widely used in textile industries and have harmful effects on the environment. They also contain carcinogenic and mutagenic substances. The goal of this study was optimization of the catalytic ozonation process using bone char ash modified by magnesium oxide in removal of reactive black 5dye from textile wastewater based on Taguchi design. Materials an...
Textile and Textile dyestuff industries discharge effluent having high Chemical Oxygen Demand (COD) and colour, making it difficult to treat the effluent completely. Several Physical, Chemical and Biological treatment methods are available to treat such an effluent. However, in recent year’s biological treatment with focus on bacteria have been drawing a tremendous attention due to their abilit...
introduction: the powdered activated carbon treatment (pact) has been proposed as an alternative in wastewater treatment and wastewater biomass protection against toxic substances. this study aims to evaluate pact performance in treating dyes, acid orange, and remazol brilliant reactive blue. methods: this empirical- applied research was carried out in pilot scale in which different dye removal...
Azo dyes are important chemical pollutants of industrial origin. Textile azo dyes with bioaccessible groups for lignin degrading fungi, such as 2-methoxyphenol (guaiacol) and 2,6-dimethoxyphenol (syringol), were synthesised using different aminobenzoic and aminosulphonic acids as diazo components. The inocula of the best biodegradation assays were obtained from a pre-growth medium (PAM), contai...
Amongst functional macromolecules, the combination of polymers and dyes is a research field of great potential with regard to high-performance materials. Accordingly, colored polymers have become increasingly important as materials for miscellaneous technical applications in recent years while also being a major part of everyday life. For instance, dye-containing polymers are nowadays widely ap...
Natural dyes have been used from ancient times for multiple purposes, most importantly in the field of textile dying. The increasing demand and excessive costs natural dye extraction engendered discovery synthetic petrochemical compounds. Nowadays, they are dominating market, with nearly 8 × 105 tons produced per year due to their wide range color pigments consistent coloration. Textile industr...
Sulfonated reactive azo dyes, such as Reactive Orange 107, are extensively used in textile industries. Conventional wastewater treatment systems are incapable of degrading and decolorizing reactive azo dyes completely from effluents, because of their stability and resistance to aerobic biodegradation. However, reactive azo dyes are degradable under anaerobic conditions by releasing toxic aromat...
Tailored ad-hoc methods must be developed for successful identification of minute amounts of natural dyes on works of art using Surface-Enhanced Raman Spectroscopy (SERS). This article details two of these successful approaches using silver film over nanosphere (AgFON) substrates and silica gel coupled with citrate-reduced Ag colloids. The latter substrate functions as the test system for the c...
A screening using several fungi (Phanerochaete chrysosporium, Pleurotus ostreatus, Trametes versicolor and Aureobasidium pullulans) was performed on the degradation of syringol derivatives of azo dyes possessing either carboxylic or sulphonic groups, under optimized conditions previously established by us. T. versicolor showed the best biodegradation performance and its potential was confirmed ...
