bokbunja seed wastes from a wine manufacturing industry were used to prepare carbon for the purpose of using it as an adsorbent for the removal of reactive blue 4 from aqueous solutions. a part of prepared carbon was treated with n-hexane to remove the seed oil present in large amounts in bokbunja seeds. it was found that the hexane treated carbon was more efficient in removing the dye from aqu...

The adsorption of textile dyes by clay was investigated using basic dye (Methylene Blue). Adsorption of dye effluent onto clay samples was carried by batch studies at room temperature, 25oC. The effects of adding clay with zeolite, pH and shaking time towards adsorption performance were investigated. The results from the mixture of 1.0 g clay and 0.01 g zeolite, the increases of pH, pH 9 and th...

one pollutant which seriously threatens water resources is dye. therefore, finding a suitable method to separate the dye in water resources is very important. an adsorption process that uses low cost adsorbents is considered as an efficient strategy for this purpose. in this study, erythrosine dye removal from an aquatic environment using natural absorbents, namely sorghum and ziziphus nummular...

This paper presents a study on the adsorption of basic dye, methylene blue, from an aqueous solution onto diatomaceous earth (diatomite). The effect of initial dye concentrations, adsorbent particle size and concentration, and agitation speed on adsorption was investigated. Adsorption isotherms obtained at different solutions temperatures revealed an irreversible adsorption with a capacity of 4...

Background: Synthetic dyes are serious pollutants and wide ranges of methods have been employed for their removal from aquatic systems. We studied the adsorption of "Nile blue A" (NBA), an anionic dye, from aqueous solution by oxidized multi-walled carbon nanotubes (MWCNTs). Methods: Scanning electron microscope and Fourier transform infrared spectroscopy were used to characterize ...

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...

In the present study, comparative batch adsorption of basic dye namely Crystal Violet (CV) using the almond shell as an adsorbent in untreated form and activated with sodium hydroxide was carried out in search of optimum adsorption conditions. The operation parameters investigated was contact time (10 to 80 min), initial dye concentrations (40-240 mg/L), temperature, (20-5...

Dye adsorption plays a crucial role in dye-sensitized solar cells. Herein, we demonstrate an in situ liquid-phase analytical technique to quantify in real time adsorption of dye and coadsorbates on flat and mesoporous TiO(2) films. For the first time, a molar ratio of co-adsorbed Y123 and chenodeoxycholic acid has been measured.

Ultra-light aerogels have been assembled from cellulose nanofibrils into hierarchically macroporous (several hundred μm) honeycomb cellular structure surrounded with mesoporous (8-60nm) thin walls. The high specific surface (193m2/g) and surface carboxyl content (1.29mmol/g) of these aerogels were demonstrated to be highly capable of removing cationic malachite green (MG) dye from aqueous media...
