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.","authors":[],"categoryName":"|","doi":"","fpage":"1951","id":"a84063c9-d2d5-44f6-a9b1-c5903e0dc5fe","issue":"19","journal":{"abbrevTitle":"ACS","id":"8740b980-5ccc-4edc-a980-54906475d995","issnPpub":"0567-7351","publisherId":"ACS","title":"Acta Chimica Sinica"},"keywords":[{"id":"f8728997-778e-41b3-a1eb-6cab7ccd24a3","keyword":"K2FeO4;stability;spectrophotometry method;electrochemical characteristics;ferrate(vi) ion;electrode;battery","originalKeyword":"K2FeO4;stability;spectrophotometry method;electrochemical characteristics;ferrate(vi) ion;electrode;battery"}],"language":"en","publisherId":"0567-7351_2004_19_1","title":"Stability of K2FeO4 in dilute KOH solution","volume":"62","year":"2004"},{"abstractinfo":"Discharge performance of K2FeO4 electrode under different conditions was studied by the constant electric current discharge method.

For the samples with x = 0.10 and 0.12, a large divergence of the ZFC and FC susceptibilities and pronounced hysteresis at low temperature are observed. However, the samples with x = 0.15 and 0.17 are antiferromagnetic with Neel temperatures of 25.4 and 25.3 K, respectively. The reciprocal susceptibility and electrical conductivity indicate that the samples with x = 0.15 and 0.17 undergo a charge separation transition from mixed/averaged valence state manganese ions to Mn(3+) and Mn(4+) between 250 and 300 K. Below half occupancy of the K(+) site (x <= 0.125), the strong geometrical frustration due to the triangular lattice configuration and the mixture of Mn(3+)/Mn(4+) result in the spin-glass behavior of the samples with x = 0.10 and 0.12. Above half occupancy of the K(+) site, the samples with x = 0.15 and 0.17 exhibit an antiferromagnetic feature due to the charge separation of Mn(3+) and Mn(4+).
