Application


  • Sodium salt promoted the generation of nano zero valent iron by carbothermal reduction: For activating peroxydisulfate to degrade antibiotic.: Research demonstrates the use of sodium nitrate in the synthesis of nano zero valent iron, which is effective in activating peroxydisulfate for the degradation of antibiotics in wastewater treatment, offering a potential solution to antibiotic pollution (Xue C et al., 2024).
