Abstract
This paper introduces three methods for preparation of potassium ferrate (VI) as a new, efficient and multipurpose water treatment agent, which is a non-toxic one as well. The mechanism of each method and the effect of raw materials on production rate and purity of potassium ferrate (VI) are studied. Merits and faults of each method are also compared. At the same time, in this paper, the chemical and physical characters of potassium ferrate (VI) are discussed. The qualitative analysis of potassium ferrate (VI) used is IR spectrum and the quantitative analysis of potassium ferrate (VI) is oxidation-reduction titration. Because of its oxidation and coagulation effect, the potassium ferrate (VI) is effectively applied in water supply works and waste water treatment.
