“…Traditionally sedimentation, coagulation or methods based on adsorption, have been used in treatment of industrial wastes. However, due to a number of drawbacks these methods often do not meet requirements of stringent quality standards [1][2][3]. As a result, in recent years continuous efforts have been made to develop innovative technologies in order to remediate polluted environment.…”

“…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.…”

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.

“…Thus their decolourization is one of the indispensable processes in wastewater treatment. A number of techniques aimed at preferential removal of different types of dyes from wastewater have been developed [2,3]. Among these physico-chemical methods like adsorption [4,5], electrochemical coagulation [6] and photocatalytic decolourization [7] are more popular now-a-days.…”

Tartrazine, a yellow menace, is widely being used in cosmetics, foodstuffs, medicines and textile. It is carcinogenic and also catalyzes allergic problems. In the present work the ability to remove Tartrazine from aqueous solutions has been studied using waste material-hen feathers, as adsorbent. Effects of pH, concentration of the dye, temperature and adsorbent dosage have been studied. Equilibrium isotherms for the adsorption of the dye were measured experimentally. Results were analyzed by the Freundlich and Langmuir equation at different temperatures and determined the characteristic parameters for each adsorption isotherm. The adsorption process has been found endothermic in nature and thermodynamic parameters, Gibb's free energy ( G • ), change in enthalpy ( H • ) and change in entropy ( S • ) have been calculated. The paper also includes results on the kinetic measurements of adsorption of the dye on hen feathers at different temperatures. By rate expression and treatment of data it has been established that the adsorption of Tartrazine over hen feathers follows a first-order kinetics and a film diffusion mechanism operates at all the temperatures.
