摘要	The stability of K2FeO4 in dilute KOH solution with initial pH value from 8.0 to 13.0 was studied in detail by spectrophotometry method in this paper. The decomposition rate of aqueous solution of K2FeO4 is basically regulated by its concentration, pH and the decomposed product FeOOH that can catalyze the decomposition of K2FeO4. The increase of HO- concentration can improve the stability of K2FeO4 by decreasing the collision frequency between FeO42- ions. However, when the concentration of HO- reaches a certain value, the decomposition product FeOOH is easily produced. FeOOH can catalyze the decomposition of K2FeO4. It was found that K2FeO4 is the most stable in the pH region of 10.0 similar to 11.0 and the decomposition rate of K2FeO4 is in the first order in the initial period. The decomposition rule of K2FeO4 along with its concentration in KOH solution is related with the initial pH of the solution.
