Activated carbon derived from biomass waste, namely palm shell, was evaluated as a potential adsorbent for the removal of Reactive Black 5 dye (RB5) from an aqueous solution. This work focused on the equilibrium isotherms and the kinetics of the adsorption process. Batch adsorption tests were conducted to determine the effects of various parameters, such as contact time, RB5 concentration, adso...

Rapid industrialization has necessitated the manufacture and use of different chemicals in day to day life. Water is life but now-a-days due to advancement in industrialization, it a spoiling a lot. In the present study, an attempt was made to examine the isolation and identification of Bacillus species from marine soil, Nagapattinum seashore, Tamil Nadu, India. Dyes are collected from in aroun...

The aim of this study was to determine the effects of main factors and interactions on the color removal performance from dye solutions using the electrocoagulation process enhanced by adsorption on Granular Activated Carbon (GAC). In this study, a mathematical approach was conducted using a two-level fractional factorial design (FFD) for a given dye solution. Three textile dyes: Acid Blue 74, ...

Natural dyes have been used for staining wool, silk, carpet and cotton in addition to their uses in staining of tissue microscopical sections. The binding of dyes to textile products has been studied for many years, but is sti l l not fully understood. Less is known about the interaction between the dye and tissue components. Black mulberry (Morus nigra) fruits have strong staining activity and...

In the present study, the decolorization and degradation of Reactive Black 5 (RB5) azo dye was investigated by biological, photocatalytic (UV/TiO2) and combined processes. Application of Candida tropicalis JKS2 in treatment of the synthetic medium containing RB5 indicated complete decolorization of the dye with 200 mg/L in less than 24 h. Degradation of the aromatic rings, resulting from the de...

Abstract We investigated the dye-removal potential of a collection 61 cold-adapted yeasts from King George Island, Antarctica, on agar plates supplemented with 100 mg L –1 several textile dyes; among which isolates 81% decolorized Reactive Black 5 (RB-5), 56% decolorizing Orange 16, but only 26% doing so Blue 19 and Acid 74. Furthermore, we evaluated ligninolytic using 2,2ʹ-azino-bis(3-ethylben...

In this research, the removal of Reactive Red 198 dye (RR-198) by Cuttlefish bone powder was investigated. The adsorbent was prepared in laboratory conditions and ground by ASTM standard sieves (60-100 mesh). The progress of the process is monitored spectrophotometrically by measuring the absorbance of dye at 518 nm wavelength. In addition, the effects of process parameter...
