In order to extend the preservation time of the ferrate, the experiment was carried out to study the type of strong oxidizer and buffering agent through static comparing test. The orthogonal test determined the best parameters of sulfate type, temperature and the dosage. The result shows that the inhibitory action of Na2S2O8 is the strongest oxidizer, and the temperature had the important role on ferrate stability. The higher temperature, the quicker the ferrate decomposition speed. The Na2S2O8 effect on stability was the best at any temperature and the dosage of Na2S2O8 could be controlled between 0.5% and 1.0%.The carbonate buffering agent could play certain stable effect, the ferrate decomposition is only 7.65% from the 2nd day to the 10th day when the mole ratio of NaHCO3 and NaOH was 2:1 and the density was the ferrate’s 100times.
