“…Removal of these dyes from wastewater is a major environmental challenge, and there is a constant need to have an effective process that can efficiently remove these dyes. Several methods have been employed to remove dye from industrial effluent, such as biological and chemical oxidation, coagulation-flocculation, foam flotation, electrolysis, biodegradation, advanced oxidation, photocatalysis, ozonation (Vandevivere et al 1998;Robinson et al 2001;Papic et al 2004;Forgacs et al 2005;Rahbar et al 2006;Sundrarajan et al 2007). Many of these methods have certain merits but require considerable operational costs (Vandevivere et al 1998;Allen and Koumanova 2005).…”

Adsorption characteristics of water hyacinth roots powder for the removal of Indosol Dark-blue GL dye were investigated in batch mode. Operating variables, such as initial solution pH, presence of detergent, adsorbent dosage, initial concentration and contact time, were studied. The results showed that the adsorption of dye increased with increasing the initial concentration and contact time. The adsorption is highly pH dependent and adsorption capacity increased with decrease in pH. Kinetic study revealed that the uptake of Indosol Dark-blue GL was very rapid within the first 15 min and equilibrium time was independent of initial concentration. Batch equilibrium experiments were carried out at different pH and found that equilibrium data fitted well to Langmuir isotherm model. The maximum sorption capacity of the adsorbent was found as 86 mg g -1 at pH 3 which reduced to 64 mg g -1 at pH 5. The presence of detergent reduced the sorption capacity of the adsorbent significantly. Using equilibrium and kinetic data, the forward and backward rate constants were determined from the unified approach model. Desorption study revealed that the dye can be recovered by swing the pH from low to high.

“…It has been estimated that more than 700,000 tonnes of dyestuff are produced annually, and about 10-15% of these dyes are left in effluents during dyeing processes [1,2]. The presence of dyes in water is aesthetically undesirable, even very low concentration of dyes is highly visible.…”

“…Dye removal by coagulation is not based on the partial decomposition of dye compounds, thus no potentially harmful and toxic intermediates are produced. Furthermore, this process can be used in large-scale operation with relatively high operability and cost effectiveness [2,11,12]. A limitation of this technique is that some high-soluble, low molecular and cationic dyes might not be effectively removed.…”

Removal of three direct dyes (Direct Black 19, Direct Red 28, and Direct Blue 86) by coagulation with three different Al based coagulants was investigated. The main purpose of this paper is to examine the coagulation features of polymeric aluminum coagulants in treatment of dye-polluted waters and the emphasis was placed on the roles of preformed Al species, particularly Al 13 . The performance of Al 13 in coagulation of dyes was observed through jar tests by comparing traditional Al salt, polyaluminum chloride (PACl), and purified Al 13 . The results showed that under most cases Al 13 had significantly higher efficiency in removal of direct dyes than traditional Al salt and commercial PACl with the exception of Direct Red 28 removal under high pH range. The coagulation of direct dyes could be greatly affected by pH. Reducing pH was favorable for preformed Al species in a broad pH range. For traditional Al coagulant, efficient dye removal only occurred in a relatively narrow pH range of near 6.0. The outstanding coagulation behavior of Al 13 could be ascribed to its high charge neutralization ability, relative stability and potential self-assembly tendency.

“…In this context, the textile industry has a significant stake in the generation of effluents with highly pollution potential, using large amounts of water with chemical additives [1]. The process of dyeing using supercritical fluids is an alternative method that does not use water and any additive is frequently not required.…”

High pressure phase behavior experimental data have been measured for the systems carbon dioxide (CO 2 ) + 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim] [PF 6 ]) and carbon dioxide (CO 2 ) + 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim] [PF 6 ]) + 1-amino-2-phenoxy-4-hydroxyanthraquinone (C.I. Disperse Red 60). Measurements were performed in the pressure up to 18 MPa and at the temperature (323 to 353 K). As reported in the literature, at higher concentrations of carbon dioxide the phase transition pressure increased very steeply. The experimental data for the binary and ternary systems were correlated with good agreement using the Peng-Robinson equation of state. The amount of water in phase behavior of the systems was evaluated.
