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
快速電解獲取高濃度na _ 2feo _ 4溶液的方法，主要包括四個方面：採用兩陰極室夾一厚度較小的陽極室的隔膜（或離子膜）電解槽；使用比表面積較大的鐵網陽極；保持陽極室中有適宜濃度的濃naoh溶液；採用較低的電流密度和較高的電解速度。具體工藝參數是： 14 16mol / lnaoh溶液、溫度303 308k 、表觀陽極電流密度300a m ~ 2 、有效單位電解速度6 . 0a / l 。 -
A modified definition of polarization resistance calculated from the equivalent circuit of eis make its value dependent on the grain size. in anodic polarization test ( sweeing and stair - steps ), the maximum ( critical ) current density increases while the passivation potential and breakdown potential lowers with the reduction of the grain size. fegsem images showed the grain growth and pitting corrosion of the nc copper surface, uniform corrosion in the mc copper surface and the broken passivation layer in both surfaces
在陽極極化實驗（包括掃描法和臺階法）中，致鈍電流雖晶粒尺寸減小而增大，而致鈍電位和擊穿電位都隨著晶粒細化而降低。 fegsem照片發現了納米晶銅的晶粒長大和孔蝕，微米晶銅表面的均勻腐蝕，和兩種銅表面破碎的鈍化膜。 -
Cyclic voltammetry indicated that the reaction mechanisms of micro - and nc copper are identical, but the anodic peaks current density of nc copper is much lower than that of mc copper. the potentiometric analysis demonstrated that the pitting corrosion seemed to happen earlier on nc copper surface than on the mc surface. the xrd found cu2o on nc copper surface while no oxide was found on mc copper surface
陽極極化實驗表明，納米晶銅的致鈍電位、致鈍電流和維鈍電流都比微米晶銅要低。循環伏安法表明兩者的反應機理沒有根本的區別，但對陽極電流峰的電流值來說，微米晶要高於納米晶，陰陽極峰的距離來說，微米晶要近一些。
