Preparation Method and Application of Magnetic Hydrothermal Carbon for Activating Persulfate to Degrade Organic Pollutants

Using corn straw powder as the raw material, the magnetic hydrothermal carbon is prepared via a one-step low-temperature hydrothermal method with urea and ferric nitrate, without the need for high-temperature calcination, featuring a simple process.

This material can serve as an activator to synergistically degrade antibiotic and dye-based organic pollutants with persulfate. Efficient degradation can be achieved by adding the activator and persulfate at specific concentrations and stirring for 60-120 minutes, and the material is suitable for the field of organic wastewater treatment.
