    Purification Process of Wastewater Containing Low Concentration of Co2+ by Neutralized Ferrite Method

    • 摘要: 采用正交试验研究了Cu2+、Zn2+、Mn2+单独作用或共存时中和铁氧体法净化低浓度Co2+废水的工艺。中和铁氧体法对Co2+、Cu2+、Zn2+、Mn2+4种离子去除效果较好,Cu2+、Zn2+、Mn2+单独作用或共存均不同程度降低了Co2+的去除效果。在各最优组合条件下,Co2+净化系数均高于1.00×104,残留质量浓度为0.40~0.50 μg/L;Cu2+、Zn2+、Mn2+的残留质量浓度均低于5 μg/L。Cu2+、Zn2+、Mn2+单独作用时各离子净化系数从大到小依次为Co2+ > Mn2+ > Cu2+ > Zn2+,离子共存时各离子净化系数从大到小依次为Co2+ > Cu2+ > Mn2+ > Zn2+,共存离子之间相互作用对铁氧体的形成具有影响。

       

      Abstract: The orthogonal experiments were carried out to study the purification process of wastewater containing low concentration of Co2+ by neutralized ferrite method at the appearance of Cu2+, Zn2+ , Mn2+ or their mixture. The neutralized ferrite process can remove Co2+, Cu2+, Zn2+ and Mn2+ efficiently, while the removal efficiency of Co2+ reduced by the appearance of Cu2+, Zn2+, Mn2+ or their mixture. Under the optimized conditions, the decontamination factors (DF) of Co2+ were all above 1.00×104, and the residual concentration was 0.40-0.50 μg/L. Moreover, the residual concentrations of Cu2+, Zn2+ and Mn2+ were all lower than 5 μg/L. With single ion, the DF sequence was Co2+ > Mn2+ > Cu2+ > Zn2+. With coexistence of Cu2+, Zn2+ and Mn2+, the sequence was Co2+ > Cu2+ > Mn2+ > Zn2+. The interactions among ions had impact on the formation of ferrite.
