Study on the Stability of Potassium Ferrate

Abstract:

The effects of potassium ferrate initial concentration, pH and inorganic salt addition on the stability of potassium ferrate were studied. The results showed that the higher the potassium ferrate initial concentration was, the poor of its stability was. The stability of potassium ferrate improved with the increase of pH. The stability of potassium ferrate got worse with the addition of inorganic salt including sodium silicate, sodium molybdate and sodium phosphate, and the law of the influence of pH on the stability of potassium ferrate was broken.
