( i ) in the procession of preparing na2feo4 by electrolyzing and oxidizing anodic iron in the high concentration solution of naoh , the current efficiency is directly proportional to both of the temperature and the alkaline concentration of the anolyte , and the growth rate of the na2feo4 concentration of anolyte is directly proportional to both of the electrolyzing speed and the alkaline concentration of anolyte . , 主要结论如下: ( 1 )在浓naoh溶液中直流电解氧化铁阳极生成na _ 2feo _ 4溶液的过程中,电解液温度、阳极液碱浓度与电流效率成正函数关系;电解速度、阳极液碱浓度与阳极液中na _ 2feo _ 4浓度的增长速度成正函数关系。
