Reactive dye is a class of highly coloured organic substances, primarily used for tinting textiles. The dyes contain a reactive group, either a haloheterocycle or an activated double bond, which, when applied to a fibre in an alkaline dye bath, forms a chemical bond between the molecule of dye and that of the fibre. The reactive dye therefore becomes a part of the fibre and is much less likely ...

One of the most environmentally friendly methods to treat wastewater, especially synthetic dyes, is production activated carbon from agricultural waste. Tamarind seeds were transformed negative-value waste into in order study removal dyes. The particular agro was soaked ZnCl2 for chemical activation increase its surface area and enhance porosity. Physical tamarind done by carbonization process ...

Previous studies suggest that reactive dyes can induce IgE mediated bronchoconstrictions. To evaluate the significance of specific IgE and IgG antibodies in workers exposed to reactive dyes, we studied the prevalence of Black GR-specific IgG by enzyme linked immunosorbent assay, as well as Black GR-specific IgE by RAST, in 176 workers employed in 1 reactive dye factory and 4 neighboring factori...

The present study describes the conductometric and spectroscopic study of the interaction of reactive anionic dyes, namely, reactive red 223 and reactive orange 122 with the cationic surfactant cetyltrimethyl ammonium bromide (CTAB). In a systematic investigation, the electrical conductivity data was used to calculate various thermodynamic parameters such as free energy (ΔG), enthalpy (ΔH), and...

Problem statement: Many studies have been conducted on the removal of either anionic or cationic dyes. However, as a mixture of dyes does commonly exist together in wastewater, therefore it is of great interest to have a material that can remove both types of dyes. Approach: To prepare an inexpensive and efficient sorbent by chemically modifying rice hull for the removal of both basic and react...

Carbon prepared from Gloriosa superba pericarp was used to remove reactive orange 107 and reactive black 5 from aqueous solution by adsorption technique under varying conditions of agitation time, dye concentration, adsorbent dose and pH. Adsorption depended on solution pH, dye concentration, carbon concentration and contact time. Equilibrium was attained at 165 minutes and 105 minutes for reac...

problematic dyes extensively used in different industries such as textile, paper, food, plasticsand cosmetics have undesirable environmental effects. white rot fungi demonstrating effective extracellularenzyme system, which is capable of degrading dyes and various xenobiotics. the aim of this study was tooptimize decolorization of reactive blue 19 (rb19) dye using phanerochaetechrysosporium. a ...
