Abstract: A novel compound adsorbent of fly ash and bentonite was synthesized and applied to adsorbing chromium(Ⅵ). The result showed that the removal ratio of Cr(Ⅵ) was over 91% under the following conditions：pH of waste water 4, initial concentration of Cr(Ⅵ) 22 mg/L, dosage of the adsorbent 8 g/L, adsorption equilibrium time 1h, temperature 25℃

摘要： 以粉煤灰和膨润土为原料，制备了粉煤灰-膨润土复合吸附剂，研究了该复合吸附剂对水中Cr(Ⅵ)的吸附性能，结果表明：在温度为25 ℃，pH值为4，Cr(Ⅵ)初始质量浓度为22 mg/L，复合吸附剂用量为8 g/L，吸附时间为1 h，Cr(Ⅵ)的去除率可达到91%以上。
