摘要
以膨润土为原料,制备了铁镍改性膨润土,研究了不同条件下铁镍改性膨润土对水中Cr(Ⅵ)的吸附性能,结果表明:在废水pH值为4,Cr(Ⅵ)初始浓度为22mg/L,铁镍改性膨润土用量为5g/L,吸附1h,温度为25℃条件下,铁镍改性膨润土对Cr(Ⅵ)的去除率达到94%以上。
Fe-Ni modified bentonie was synthesized and applied to adsorb Cr（Ⅵ）-containing wastewater. The results show that the removal ratio of Cr（Ⅵ）is over 94% under following conditions： the pH value of the wastewater is 4, initial concentration of Cr（Ⅵ） is 22mg/L, the dosage of Fe-Ni modified bentonite is 5g/L, the adsorption time is 1h, and the temperature is 25℃.
