Abstract


The paper deals with the adsorption of direct dye from aqueous solution onto waste ashes prepared from the heating station of Leskovac (Serbia). Waste ashes are used for the reduction of coloration, for example, of textile wastewater. Based on the results, it can be said that the waste ashes are an efficient adsorbent for the removal of direct dye from aqueous solution. Prolonged contact time means a greater amount of color on the adsorbent, i.e. the dye concentration in the solution decreases with the adsorption duration. The typical graphical representation obtained from the Freundlich equation shows that this model provides a sufficiently accurate description of the experimental data of dye adsorption on waste ashes as opposed to the Langmuir model.
