A bacterial strain SVM1 with remarkable ability to decolorization textile dye Reactive Red ME4BL was isolated from the activated sludge soil collected from a common effluent treatment plant (CETP) in Perunduari, Erode district Tamil Nadu. Different parameters such as temperature and pH were optimized for decolorization of Red ME4BL by using isolated bacteria. The most promising bacterial isolat...

Y3Al5O12:Ce3+ (YAG:Ce3+), the most common yellow phosphor for WLEDs, has a red insufficiency in its light spectrum. The Ce3+ spectral profile is modified this research using surface-located ATTO-Rho101 dye molecules, which have powerful, wide impregnation greenish-yellow spectroscopic zone of radiation and vivid red-emitting radiation. To create spherical shell evenly dispersed micro nanometer ...

The present study investigated the ability of modified shrimp shell by Polyethylenimine (PEI) for enhanced removal metanil yellow. modification was carried out using citric acid as a cross linker. yellow shell-PEI conducted batch method and some parameters affected adsorption including pH, initial dye concentration, contact time. optimum conditions were achieved at pH 5, concentration 1200 mg/L...

The adsorption removal of Triphenylmethane & Xanthene dyes onto a low-cost coal based adsorption (Charfines) and its efficiency in dye colour sorption was compared with activated carbon (F-400). Batch studies were performed and the results revealed that Charfines demonstrated on ability to adsorb the reactive Triphenylmethane & Xanthene dyes. The sorption interaction of reactive dye on to Charf...

PD/CC@SiO 2 core–shell nanoparticles (PD: perylene dye, CC: cholecalciferol/vitamine D 3 ) show high colloidal stability in water, intense emission from red to yellow with quantum yields near unity, and excellent photostability.

OBJECTIVE The present study was carried out to evaluate the toxic effect of blend of some food colors on Swiss albino rats. MATERIALS AND METHODS A blend (1:1:1) of sunset yellow, metanil yellow and tartrazine showed additive effects on serological parameters which indicate that addition of these dye together in food stuff may give rise to more toxic effects than are produced by each dye indi...

The textile dyes are considered as major environmental problems. The dyes can be removed by various methods. Therefore, this study aimed to evaluate the adsorption rate of Reactive Red 198 (RR198) from aqueous solution by activated Azolla filiculoides. This was an empirical-lab study. The Azolla was used as an adsorbent to remove Reactive Red 198 dye. The effect of various parameters was invest...
