Abstract

Flyash is the waste material from thermal power plant. This is produced in abundance globally and poses risk to health as well as environment. Thus their effective utilization has always been a challenge for scientific community. Hence, the study was performed to use the waste material i.e. flyash as a low cost adsorbent for decolourization of disperse dye from aqueous solution through column technique. Column experiments were carried out at equilibrium condition for different concentrations of disperse blue 354 ranging between (1-20) ppm, respectively. The column was packed using different combination of flyash and sand (1:1, 1:2 and 1:3). The removal of disperse dye from column experiments decrease with the increase in solution concentration at room temperature, showing the process is dependent on the initial concentration of the solution. The percentage removal of dye by adsorption was found to be 82% at lower concentration and 69% at higher concentration for disperse blue 354, respectively.
