摘要
The invention concerns a method for preparing an alkali metal ferrate, which comprises the following steps: (i) preparing a reaction mixture comprising at least an iron salt, at least an alkali or alkaline-earth metal hypochlorite and an alkali metal hydroxide; (ii) heating the mixture prepared at step (i) to a temperature ranging between 45 and 75° C., so as to form the alkali metal ferrate; (iii) recuperating the alkali metal ferrate formed at step (ii). The invention also concerns novel alkali metal ferrates.
