Abstract:
Ferrate(VI) technology for waste water treatment has been considered for a long time and being a „green” procedure it is still intensively studied. Several reviews are available on various aspects of the industrial applications. The greatest advantage of this method is that it avoids the application of chlorine, and the end products of the oxidative destruction of the organic pollutants in water are iron(III) oxyhydroxides which are not poisonous, and since they precipitate from the water, the surface of the these particles adsorbs more pollutants and remove them from the wastewater by coagulation. In this work we report on measuring the ferrate(VI) content of an electrochemically prepared potential industrial product on long term storage and make an attempt to identify the iron(III) degradation products.
