Fe-based amorphous materials have attracted extensive attention in the application of organic pollutant degradation due to their excellent chemical properties. In this work, a novel Fe-based (Fe-Si-B-P) amorphous powder prepared by gas atomization is employed to decompose azo dyes for wastewater treatment. Its crystalline structure, distribution of particle size, and soft magnetic properties are characterized. The experimental results show that the Fe-based (Fe-Si-B-P) powder is amorphous morphology which might bring many benefits for decomposing organics in waste water. The particle size of the micro-sized spheroidal powder distributes mainly from 10 to 50 μm, and most are about 17~19 μm. The magnetic properties are also investigated. Its saturation magnetization (MS) and coercivity (HC) are, respectively, 55 emu/g and 19.6 Oe, which present superb soft magnetic properties. Finally, we studied the degradability of the Fe-based amorphous powder by decomposing the methylene blue in waste water, and the results show that 0.05-g Fe-based amorphous powder can completely degrade the 50 ml methylene blue solution with the concentration of 3 × 10−5 M within 15 min in weak acidic environment, which shows great degradability for wastewater treatment.
