We studied the adsorption of acid blue 129 ions on Mg-bentonite clay from aqueous solution at different temperatures (Fig. 2). The results make it clear that the adsorption on Mg-bentonite clay increases with time. Furthermore, the dye uptake by activated Mg-Bentonite clay was rapid initially up to 25 minutes, followed by a continued rise up to 40 minutes, and 5.397×10-6 mol g-1 of AB129 was

The adsorption capabilities of raw bentonite and its modified form were examined through their use in the removal of Acid Blue 129 from aqueous solution. The adsorption isotherm and kinetic experiments were conducted at four temperatures (25, 30, 40 and 50 ºC). The fitting of the corresponding experimental data was tested using the temperature-dependent forms of the Langmuir, Freundlich,

A very little amount of dyes in water are visible and they affect the eco system of water [Mishra and Tripathy 1993]. The dye should be removed from the waste water before it is discharged into water bodies. Even though so many methods are available, adsorption method [Kannan and Meenakshisundaram 2002] is the best one to remove dye from waste water. The Literature collections
