Fe(VI) is a powerful green oxidant with a reduction potential being 2.2 V under acidic condition, even greater than ozone. It is generally converted into Fe(OH)3, a non-toxic final product. The present study uses wet chemical method to prepare K2FeO4 with a waste steel pickering liquid that is rich in FeCl2. Chemicals used for the preparation are NaOH, KOH, and small amount of organic solvents like methanol and ether for final washing of the reaction product. Purity of the homemade K2FeO4 is greater than 90%, comparable to a commercial product. De-colorization rate of methylene blue in water solution with the K2FeO4 is rapid, reaching colorless in a few seconds in a test with Fe/C mole ratio of about 1/1. X-ray absorption technique reveals that the homemade K2FeO4 comes with an even greater pre-edge peak than a commercial product does, indicating a higher purity than the commercial one. Experiments for determining a total mass balance of Fe, Na, K, and Cl are completed to provide necessary information for evaluating the cost of preparing the K2FeO4.
Yu-Ling Wei completed his PhD from Penn State University in 1985 and has served as a faculty member for Tunghai University of Taiwan since 1987.
