The distinct anodic current peak was observed in the seawater containing srb . it was presumed that it was the result of electrochemical oxidation of sulfide 在接近自然腐蝕電位( ecorr )附近,出現(xiàn)了顯著的陽極電流峰值,電流峰值是硫化物氧化的結(jié)果。
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(gè)方面:采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(wǎng)陽極;保持陽極室中有適宜濃度的濃naoh溶液;采用較低的電流密度和較高的電解速度。具體工藝參數(shù)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 。
As for the method of preparing solid potassium ferrate from electrolytic synthesis of sodium ferrate solution , it is compared that the effects of the main procession facts of electrolysis upon both the anodic current efficiency and the relative concentration of na2feo4 . one method was put forward to obtain high concentration of na2pe04 in the high concentration of alkaline by quick electrolyzing iron anode 針對(duì)由電解法合成na _ 2feo _ 4溶液進(jìn)而制備固態(tài)k _ 2feo _ 4的方法,通過比較研究電解過程中主要工藝因素對(duì)陽極電流效率和相應(yīng)na _ 2feo _ 4濃度的影響,提出了在濃堿液中快速電解鐵源陽極獲取高濃度na _ 2feo _ 4溶液的方法。
