本文对铅及铅—锑合金在硫酸水溶液中作析氧阳极的氧化特点、腐蚀行为及极化特性进行了研究。结合硝基苯电解还原制对氨基苯酚这一过程，在实验室小试及工厂中试的基础上，讨论了该类阳极加工、维护及操作等问题。 In this paper, the oxidation characteristics, corrosion behavior and polarization characteristics of lead and lead-antimony alloys in sulfuric acid aqueous solution were studied. Combined with nitrobenzene reduction of p-aminophenol, this paper discussed the processing, maintenance and operation of such anodes on the basis of laboratory tests and pilot plant tests.
