Bivalent and trivalent iron inorganic compound suitable fo sgnthesizing perferrate

Abstract

The invention relates to manufacturing new type ferrous and ferric iron inorganic compound applied in electrosynthesis ferrate. They are used as anode material to form ferrous at alkali condition, restrains electrochemistry bleeding oxygen reaction. The compound has good reversibility. Thus it can use as green quadric chemical electric power source anode material. The material manufacturing is easy to do industrialization production. The raw material can utilize blue dust with low price. Its manufacturing process is simple. It is good for environment, and can fully reclaim blue dust.

Description

technical field The invention belongs to the fields of novel green chemical power sources, water pollution treatment and industrial dust treatment. Background technique The green secondary chemical power source has many advantages such as high specific energy, long cycle life and environmental friendliness, and has been widely valued in the past ten years. At present, there are many kinds of chemical power sources that can be called green secondary chemical power sources, such as nickel-metal hydride batteries and lithium-ion batteries. These chemical power sources are all single-electron processes in terms of charging / discharging principle, so there are some limitations inevitably. And emerging in recent years about high-iron battery (the valence of iron in the positive electrode material of this battery is +6) research and the published patent (such as CN 1416190A) show that it is possible to make it a member of the green secondary chemical power source family potentiall...

From the principle of sewage treatment, the current electrochemical treatment method uses hypochlorous acid as the electrogenerated oxidant, but it has been found that ferrate has advantages that hypochlorous acid does not have, such as: it will not make the treated sewage Contains chlorinated substances, these chlorinated substances often have certain toxicity and carcinogenic potential
