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22mg/L,复合吸附剂用量为8g/L,吸附时间为1h,Cr(Ⅵ)的去除率可达到91%以上。[著者文摘]

Abstract:
A novel compound adsorbent of fly ash and bentonite was synthesized and applied to adsorbing chrornium(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 1 h, temperature 25℃.[著者文摘]
