摘　　要：采用双阴极室隔膜电解槽,以多孔圆筒铸铁为阳极电解制备水处理剂高铁酸盐。实验表明,所用电解槽与平板铸铁阳极电解槽相比可得到更高的电流效率和更高浓度的高铁酸盐。在14mol/L的氢氧化钠溶液中加入0.1%(质量分数,下同)氯化钠,30℃下以30mA/cm2的电流密度电解6h,电流效率高出36.2%,高铁酸根离子浓度达0.07mol/L。The water treatment agent ferrate is prepared by electrolysis in diaphragm bath with double cathode chamber and porous cylinder cast iron anode. The experimert results show that compared with the plate iron electrolytic bath, the higher current efficiency and higher concentration of ferrate can be obtained in new bath. When 0.1% NaC1 is added into the 14 mol/L NaOH and electrolyzed at current density 30 mA/cm^2 for 6 h,the current efficienty will exceed 36.2% and the concentration of FeO^2-4 will reach 0.07 mol/L.
