METHODS OF SYNTHESIZING AN OXIDANT AND APPLICATIONS THEREOF

摘要

Methods and devices for synthesizing ferrate and uses thereof are described. One aspect is a method for continuously synthesizing ferrate comprising: continuously providing an aqueous solution comprising an iron salt in a reaction chamber, where the reaction chamber comprises at least two electrodes; providing sufficient electric current to the at least two electrodes to convert at least a portion of the iron salt to ferrate; delivering at least a portion of the ferrate to a site of use that is proximal to the reaction chamber; and adding additional aqueous solution to the reaction chamber. Another aspect is a device comprising: a reaction chamber comprising two electrodes and a solution of an iron salt, where the electrodes provide sufficient electric current to convert the solution of an iron salt to a solution of ferrate; a holding chamber controllably connected to the reaction chamber, into which the solution of ferrate is kept for a period of time; and an output opening in the holding chamber through which the mixture is adapted to be transported to a site of use, wherein the site of use is proximal to the holding chamber.
