application of pomegranate seed powder in the removal of reactive red 198 dye from aqueous solutions
industrial effluents, especially the textile industry are discussed as one of the fundamental problems of the environment .dyes are materials with complex structures that enter into the wastewater from different stages of the textile industry. colors are often toxic, carcinogenic and mutagenic. this study investigated the absorption efficiency of reactive red 198 dye from aqueous solutions by p...
The elimination of Reactive Red 120 (RR120) from synthetic solution using biochar generated Ulva prolifera was investigated. process parameters sorbent dose (A), pH (B), initial dye concentration (C), and temperatures (D) were optimized response surface methodology (RSM). To estimate the removal effectiveness with best 27 trails, Box-Behnken method (blocked) utilised. Analysis variance (ANOVA),...
Comparative study of the removal of the dye Reactive Red 120 (RR-120) from aqueous effluents from textile industry using microalgae Spirulina platensis (SP) and commercial active carbon (AC) were carried out. The batch adsorption systems were evaluated with respect to pH, agitation time, temperature and initial concentration of the dye. The maximum adsorption capacity for dye RR-120 were found ...
Background and Objective: Reactive Red 198 is a mono azo dye widely used in the textile industry of Iran. The toxicity of reactive dyes is higher than other dyes and causes disorders such as irritation, cancer and mutation in humans. The overall objective of this study was to determine the efficiency of a Constructed Wetland pilot system with conventional and baffled horizontal subsurface flow ...
in this work, response surface methodology (rsm) and artificial neural network (ann) were used to predict the decolorization efficiency of reactive red 33 (rr 33) by o3/uv process in a bubble column reactor. the effects of four independent variables including time (20-60 min), superficial gas velocity (0.06-0.18 cm/s), initial concentration of dye (50-150 ppm) and ph (3-11) were investigated us...
The oxygen-labile, activating enzyme for iron protein from the photosynthetic bacterium, Rhodospirillum rubrum, was purified 11,800-fold using a combination of chromatophore washing, DE52-cellulose chromatography, hydroxylapatite chromatography, reactive red-120 cross-linked agarose chromatography, reactive red-120 cross-linked agarose chromatography, and Sephadex G-75 gel filtration. Activatin...
