Introduction: The dye wastewaters of textile industries are often toxic and persistent in the environment. In previous years, various methods are considerate in the removal of reactive dyes. Reactive red 198 dye is one of the mono azo dyes that is now used in textile industries. The aim of this study was to investigate the efficiency of Russian Knapweed Flower powder in the removal of reactive ...
Background and Objective: Dyes have complicated structures, usually toxic and resistant to biological treatment which entered to environment by industrial waste streams. The aim of this study was the survey of isotherm and kinetic adsorption studies of Reactive Blue 19 (RB19) dye onto Barberry stems powder from textile industrial wastewater. Materials and Methods: This study was done i...
Background and purpose: Adsorption processes are widely used in removing pollutants from waste waters, particularly those that are not easily biodegradable such as dyes. In this study natural zeolite, which is easily found in many places, was used as a low-cost adsorbent for removal of dye from effluents. Materials and methods: Adsorption of Azo dyes including two basic and one reactive (React...
The ability of a particular banana fibre in removing reactive dyes from textile wastewater was studied in the present work. Locally available ground seeded banana fibre of ≤ 212 μ was used as adsorbent. Initially the adsorbent was tested on standard Novacron Blue FN-R reactive dye solutions and then it was also applied to raw textile wastewater. The adsorbent was found very effective to remove ...
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...
Activated carbon prepared from Euphorbia tirucalli L wood (ETAC) by chemical activation with phosphoric acid has been analysed for the removal of Reactive Red and Reactive Blue dyes from aqueous solutions through batch adsorption technique. Lower solution pH favours the adsorption of reactive dyes. The amount of dye adsorbed per unit mass of adsorbent increases with the increase in temperature ...
Adsorption of reactive orange 16 by quaternary chitosan salt (QCS) was used as a model to demonstrate the removal of reactive dyes from textile effluents. The polymer was characterized by infrared (IR), energy dispersive X-ray spectrometry (EDXS) analyses and amount of quaternary ammonium groups. The adsorption experiments were conducted at different pH values and initial dye concentrations. Ad...
Backgroud and purpose: Dye is one of the problems of industrial effluent such as textile industries. The dyes can be removed by various methods. Therefore, the aim of this study was the evaluation of adsorption rate of reactive red 198 from aqueous solution by activated red mud. Materials and methods: This research was a lab study. Activated red mud was used as an adsorbent to remove reactive r...
Introduction: Dyes are one of the most important existing pollutants in textile industrial wastewater. These compounds are often toxic, carcinogenic, teratogenic, and non- biodegradable. Carcinogenic and mutagenic potential of some azo dyes as a category of common dyes in different types of industries has been reported. Reactive red 198 is one of the azo dyes that are currently used in the text...
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 ...
