Electrolytic potassium permanganate is an industry with high consumption of resource and energy,serious pollution.Therefore,it is imperative to develop a new process to improve the efficiency in electrolytic process.The electrolytic process of potassium permanganate is affected by both the characteristics of nonequilibrium thermodynamics and the kinetics of hybrid factors.In the process of electrolytic potassium permanganate,the effects of the electrolysis system and the non-linear coupling factors,including the changes of ion concentration,anode current density,electrolysis temperature and electrolysis time,were reviewed.It is pointed out that the continuous electrolysis should be carried out in the sealed reactor,in order to realize resources recycling and achieve the target of energy conservation and consumption reduction.
