摘要: 以某转炉尘泥的磁选尾矿为原料,研究其对铜离子的吸附效果和吸附行为。结果表明:尘泥磁尾去除铜离子的适合条件是尘泥磁尾投加量为8.0g/L,铜离子初始浓度为20 mg/L,反应时间为50 min,此时Cu2+去除率为97.86%。吸附行为的影响因素依次为尘泥磁尾投加量>铜离子溶液初始浓度>反应时间。吸附反应以表面吸附为主,伴随少量置换反应。

Abstract: The absorption effect and absorption behavior of tailings of magnetic separation of converter sludge as test samples on copper ion were investigated.The results show that removal rate of Cu2+ can reach 97.86%, companying with the suitable conditions, that is, the tailings of magnetic separation of converter sludge of 8.0 g/L in dosage, concentration of Cu2+ of 20 mg/L and the reaction time 50 min.The importance of adsorption factors are shown as follows:the dosage of tailings > initial concentration of copper ion solution> reaction time.The adsorption reaction mainly consists of the surface  dsorption with somewhat replacement reaction accompanied.
