The removal ofxylenol orange from aqueous solution onto the coal ash was investigated at room temperature. The results show that the adsorption capacity of xylenol orange increased as the adsorption time increased and then equilibrium established after 30 min adsorption time. The results obtained revealed that the coal ash removed about 80 % of xylenol orange from the aqueous solution withi...

background dyes are one of the most important industrial pollutants, especially in textile industries. many methods have been proposed in order to remove color from wastewater among which, adsorption is more acceptable due to the ability for its use in the large scale. objectives the objective of this study was to investigate pumice as an inexpensive adsorbent for removal of methylene blue from...

considering the point that the existence of heavy metals in the wastewater are so dangerous forthe environment and it would have many bad consequences for all the creatures including human beings, wemust try out the ways that make us capable of adsorbing these heavy metals. in order to accomplish this goal we should use a method called adsorbing. in this study the adsorption of copper ions in h...

Phosphorus sorption characteristics of some Indian representative agricultural soils belonging to four soil orders namely Vertisol, Inceptisol, Alfisol and Ultisol were investigated for adsorption behaviour of P and sorption data were fitted to Langmuir and Freundlich equations. The Langmuir constant i.e. adsorption maxima was highest for Vertisol (716.85 μg g -1 ), followed by Ultisol (633.3 μ...

This paper presents the feasibility of removal of MB dye from aqueous solution using activated carbon prepared from Usoro fiber (Adenia lobata). FTIR analysis revealed that many functional groups were present on the surface of the adsorbent. The adsorption Kinetics was analyzed by pseudo first order, pseudo second order and intra particle diffusion kinetics models. Results showed that MB adsorp...

This paper presents the adsorption of crystal violet (CV+) from aqueous solution on surfactant-modified dolomite. Liquid phase batch operations were carried out to observe the effect of various experimental parameters such as initial dye concentration, adsorbent dosage, pH and NaCl concentration. The optimum conditions for these parameters were calculated by Taguchi method. Equilibrium isotherm...

In this study, biochar derived from Jackfruit peel (JA) via the pyrolysis at 500 °C for 2 h was used as an adsorbent to remove Methylene Blue (MB) aqueous solution. Effects of pH, contact time, and initial MB concentration were investigated. Isotherm models, such Langmuir, Freundlich, Sips, Dubinin-Radushkevich, applied estimate adsorption in nature. The results indicated that Sips Freundlich m...

C-phycocyanin is a natural blue dye extracted from Spirulina platensis, which has many applications in the food and pharmaceutical industries. In this paper the effect of pH and temperature on the adsorption of C-phycocyanin onto two different ion exchange resins (Streamline DEAE and Streamline Q XL) for expanded bed adsorption chromatography was investigated. Moreover, the kinetics and adsorpt...
