中文摘要 | An electrosynthesis in concentrated NaOH electrolyte is first presented for the synthesis of 0.83 mol.L-1 Na2FeO4 solution, and then for the synthesis of solid K3Na(FeO4)(2) with high purity and yield. The synthesis conditions have been explored. Many experiment techniques have been used to characterize the obtained solid sample. The experiment results showed that in the mixed NaOH-KOH solutions, the dissolution-precipitation curve of K3Na(FeO4)(2) conformed to the empirical foumula of [Na+][K+](3) x [FeO42-](2.8) = 1.4 x 10(-4) ([K+] <= 1.01 mol.L-1). The measured solubility of K3Na(FeO4)(2) in concentrated KOH electrolytes was almost the same as that of K2FeO4. Different from K2FeO4 crystals, the synthesized K3Na(FeO4)(2) powders exhibited three characteristic IR absorption peaks (787, 801 similar to 802 and 858 similar to 862 cm(-1)) and a hexagonal unit cell with the space group P3 ml (164). The results of TG/DSC experiments showed that the K3Na(FeO4)(2) powders would not decompose until 197 degrees C in the atmosphere of Ar, but were less stable than K2FeO4. |
