摘要
在重金属废水处理中,天然磁黄铁矿与人工合成的硫化铁相似,具有满意的处理效果。在一定条件下,Cu^(2+),Cd^(2+),Pb^(2+),As(Ⅲ),As(Ⅴ)和Cr(Ⅵ)的去除率在98％以上,出水As(Ⅲ),As(Ⅴ)和Cr(Ⅵ)含量可达饮用水标准。同时还发现,单斜磁黄铁矿的处理活性要比六方磁黄铁矿的处理活性强一些。
The behavior of natural pyrrhotite in the treatment of was-tewater containing heavy metals is similar to that of synthetic ferrous sulfide more than 98% of Cu, Cd, Pb, As(Ⅲ),As(Ⅴ) and Cr (Ⅵ) was removed under certain conditions using natural pyrrhotite. After the treatment, the content of As(Ⅲ), As(Ⅴ) and Cr(Ⅵ) in the water could even reach the standard for drinking water. It was also found that the activity of monoclinic pyrrhotite for the treatment of the water was stronger than that of hexagonal pyrrhotite.
