1. the method for a rapidly preparing ferrate solution by microwave radiation, is characterized in that, comprises the steps:

  • A. strong base solution is added reactor, drop into ferroferric oxide powder, heated and boiled is to nearly pasty state;

    Described ferroferric oxide powder and strong base solution mass ratio are 1;

    2~

    6, and strong base solution concentration is 25~

    45%;

    Described highly basic is NaOH or KOH;

    B. adding available chlorine is 8~

    15% NaClO solution, reacts under electromagenetic wave radiation 0.5~

    5 minute;

    The mass ratio of ferroferric oxide powder and NaClO solution is 1;

    2~

    8;

    C. through centrifugal or filtration, can obtain ferrate solution.
