| 摘 要： | 利用双氧水直接氧化硫酸亚铁,采取程序控温的方法,得到盐基度较高的PFS.探究制备硫酸亚铁的最佳合成条件,并利用此产品对含镍废水进行处理.结果表明：当n（H2O2）∶n（H2SO4）∶n（H2O）∶n（FeSO4.7H2O）为2.3∶0.3∶0.83∶1时,制得符合GB 14591-2006且盐基度高达15.63的液体PFS.利用此产品对含镍废水进行处理,除镍率可高达99.8%.

| Abstract: | By using hydrogen peroxide directly oxidize ferrous sulfate,adopting the method of temperature control program to get the high basicity degree of Polymeric Ferric Sulfate（PFS）.And studied the best synthetic condition of preparation of ferrous sulfate,then dealt with the waste water containing nikel by this product.The results shown that when n（H2O2）∶n（H2SO4）∶n（H2O）∶n（FeSO4·7H2O） was 2.3∶0.3∶0.83∶1,the PFS with basicity of 15.63 could be got,which was accord with GB 14591-2006.The removal rate of nickel in waste water could up to 99.8% after being processed with the product. |
