In this study, preparation and application of novel biocomposite materials for textile dye removal which are produced by immobilization of specific bacteria onto electrospun nanofibrous webs are presented. A textile dye remediating bacterial isolate, Clavibacter michiganensis, was selected for bacterial immobilization, a commercial reactive textile dye, Setazol Blue BRF-X, was selected as the t...

Low-cost grapefruit peel (Agricultural Waste) was used for removal of reactive blue19 dye fromaqueous solutions. The process was studied as a function of contact time, initial dye concentration andpH. Adsorption process was attained to the equilibrium within 45 min for initial dye concentrations of 50,75, and 100 mg L-1. An acidic medium was the optimum condition for adsorption of dye at roomte...

This study examined the photolytic degradation of C.I. Acid Red 73 AR73 diazo dye, in aqueous solution by combined UV, hydrogen peroxide and KMnO4. A continuous circulated photoreactor equipped with a low pressure mercury lamp 15 W, emission 253.7 nm was used. In the first step, potassium permanganate was used for decolourisation of AR73 dye solution. The effect of the key operating variables s...

The ability of waste banana pith to remove Congo red from aqueous solution was investigated. Various parameters such as initial dye concentration, contact time, adsorbent dosage and pH effect were studied. The adsorption rate constant was found to be 1 X 10. min'} at 50 mg I-I dye concentration. Above 92% removal was observed in the pH range 2-11. The removal of dye by banana pith is mostly due...

the nano sized tio2 and zno are the most active photocatalysts.  methylene blue was used as a reference molecule for the photocatalytic degradation. the tio2 and zno can totally remove methylene blue dye. the effect of various process parameters like initial concentration, contact time, dose of catalyst and ph on the extent of removal of dye by photocatalysis in presence of tio2 and zno was stu...

background; recently, there has been a great concern about the consumption of dyes because of their toxicity, mutagenicity, carcinogenicity, and persistence in the aquatic environment. therefore, the aim of this study was to determine the feasibility of using lemna minor for acid blue 292 (ab292) dye removal from aqueous solution and to determine the optimal conditions. methods; this experiment...

Background: Colors are very useful in different industries such as textile and leather but when they enter water, can cause many biological and environmental problems. In the present research, a waste agricultural material which is freely available is employed to analyze its efficiency for removing acid dye from contaminated wastewaters. Methods: In this study, batch adsorption experiments wer...

BACKGROUND AND AIM Water resources pollution control is one of the main challenges of our time for researchers. Colored wastewater discharges caused by textile industry activities has added to the concern. In this study, removal of Acid Orange 7 dye (AO7) using Kenya Tea residue absorbent (granular) has been studied. METHODS This cross-sectional study was conducted in 2016. In this work, init...

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...
