保持阳极 meaning in English

holding anode

The method of obtaining high concentration of na2feo4 solution by quick electrolysis mainly contains four aspects : adoption of either a diaphragm or an ionic membrane electrolytic cell in which a thin anodic cell lying between the two cathodes , ( 2 ) using an iron anode that has larger specific surface area , ( 3 ) keeping suitable concentration of naoh in the anodic cell , adoption of lower current density and higher electrolyzing speed . the practical technique parameters follow a s below : the naoh solution of 14 - 16mol / l , the temperature of 303 - 308k , the surface anodic current density of 300a / m2 , the unit electrolyzing speed of efficiency larger than 6 . 0a / l
快速电解获取高浓度na _ 2feo _ 4溶液的方法，主要包括四个方面：采用两阴极室夹一厚度较小的阳极室的隔膜(或离子膜)电解槽；使用比表面积较大的铁网阳极；保持阳极室中有适宜浓度的浓naoh溶液；采用较低的电流密度和较高的电解速度。具体工艺参数是： 14 16mol / lnaoh溶液、温度303 308k 、表观阳极电流密度300a m ~ 2 、有效单位电解速度6 . 0a / l 。
