Abstract: The ability of fly ash to remove acidic golden G from aqueous solutions was examined. Contributing factors to the adsorption effectiveness, including the amount of fly ash added, the pH of solution and temperature for the activation of fly ash, were investigated. It can be shown that the adsorption effect of fly ash on acidic golden G was surprisingly excellent. On most occasions surveyed in this study, the dye can be completely adsorbed by certain amount of fly ash. The optimum parameters recommended were pH 5~6.5, and activation temperature 300℃ respectively.
