AI Technical Summary
Existing iron-based alloy powders and strips, when used to degrade azo dye wastewater, suffer from high degradation efficiency but insufficient cycle stability and recycling convenience, making it difficult to achieve both high-efficiency degradation and convenient recycling in industrial applications.
A hollow-structure iron-based alloy magnetic rotor was fabricated using 3D printing technology. Its magnetism and an external magnetic field were used to achieve non-contact stirring, which was combined with a Fenton-like reaction for catalytic degradation. By adjusting the magnetic stirring speed and porosity, the specific surface area and mechanical strength were increased, achieving rapid and efficient degradation.
It achieves rapid and efficient degradation of organic pollutants in a closed container, with high degradation rate and good stability. It is easy to recycle and is suitable for the degradation of a variety of azo dyes and toxic organic pollutants. The degradation rate can reach more than 95%, and it can be recycled more than 40 times.
