【摘要】 将制备高铁酸盐后所留的氢氧化铁残渣制成六氟合铁酸钾再与次氯酸钠的高碱度溶液反应,第二次生成高铁酸盐溶液。随后用制得的含氟的高铁酸盐溶液处理甲基橙有色配水,其最佳pH在7.0左右,质量浓度为20 mg/L的甲基橙的水样500 mL,耗用17 mg的高铁酸钾,脱色率可达95%以上,处理后的水体中氟离子残留量低于国家排放标准。制得的含氟的高铁酸盐溶液作为脱色的水处理剂不会引起二次污染,工艺可行,效果良好。
【英文摘要】 The dregs of ferric hydroxide in the preparation of ferrate was to be converted into potassium fluoferrite first,then the potassium fluoferrite was put into the high-alkali solution of sodium hypochlorite and ferrate was generated again.The colored water containing methyl orange was treated with the ferrate solution containing fluorine.The best pH value was about 7.0 in treated water,and 500 mL colored water containing 20 mg/L methyl orange could be treated well with 17 mg potassium ferrate.The results show...
