摘要： 实验测定了粉煤灰对酸性金黄G染料废水中酸性金黄G染料的吸附效能。研究了加灰量，pH值及活化处理温度对粉煤灰吸附效能的影响。结果表明：粉煤灰对酸性金黄G染料有极明显的吸附效能，可具有极好的以废治废效果；随着粉煤灰的加入，染料去除率大幅度提高，对于染料浓度低于50mg/L的溶液，去除率可达到100%；吸附pH值范围为5~6.5，活化温度为300℃时，粉煤灰的吸附能力最强。

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.
