| 摘 要： | 通过正交试验,确定聚硅酸铝铁的最佳制备条件为n(聚硅酸):n(Al3+)=2:1,n(聚硅酸):n(Fe3+)=2:1,浸出液pH为4.3,熟化温度为60℃.用分光光度法研究其对Ni2+的吸附性能,结果表明:当废水pH为8.0、絮凝剂用量为20 mL/L时,Ni2+去除率达92.7%,沉降时间为16 min.

| Abstract: | The optimum experimental conditions for preparation of polysilicate aluminum ferrit were obtained by orthogonal test.Nickel-containing wastewater was treated with polysilicate aluminum ferrit and the removal rate was determined by spectrophotometry.The results showed that the removal rate of Ni2+ could reach 92.7% when n(polysilicate) : n(Al3+) was 2∶ 1,n(polysilicate)∶ n(Fe3+) was 2∶ 1,temperature was 60 ℃,wastewater pH was 8,and the usage of flocculant was 20 mL/L,and sedimentation time was 16 min,respectively. |
