Abstract

The invention relates to a process used for preparing ferrate salt with an on-line wet chemical method. The process is characterized in that a mixed solution of NaOH and NaClO of a first storage tank and solid FeNO3 delivered by a conveyer belt or a FeNO3 solution of a third storage tank are delivered into a second mixing storage tank or a static mixer and are sufficiently mixed, such that a reaction mixed liquid is obtained. The reaction mixed liquid is delivered into an annular pipe, and ferrate salt liquid product is obtained from a liquid outlet of the annular pipe. The invention also provides a device suitable for the process. With the process and the device, liquid ferrate salt can be produced on line intermittently or continuously, and waste caused by ferrate salt purification and re-dissolving is avoided. The process and the device have the advantages such as reasonable structure, high production efficiency, low preparation cost, and the like.

Description

technical field [0001] The invention relates to a preparation method of an inorganic chemical material, in particular to a process and a device for preparing ferrate by an online wet chemical method. Background technique [0002] Ferrate has strong oxidizing properties due to the valence of iron being +6. In alkaline solution, its redox potential is 0.72V, and in acidic solution, its redox potential is 2.2V. Ferrate has a wide range of applications. It can replace other highly toxic oxides in organic synthesis and selectively oxidize certain functional groups. For example, it can oxidize primary and secondary alcohols to aldehydes and ketones, respectively. Due to FeO 4 2- It has high discharge capacity, so it has received great attention in the field of batteries, and it is expected to replace the cathode materials in traditional batteries. Ferrate can also be used as an ideal magnetic memory material to prepare a magnetically controlled release system with ferrate as th...
