AB  - Pathogenic viruses in water are seriously harmful to human health and highly 
      resistant to conventional disinfections. As a kind of promising attempts for 
      pollution remediation, Fe-based nanoparticles show excellent performance in 
      removing contaminants. In this study, the Fe/Ni nanoparticles (Fe/Ni NPs) were 
      synthesized using the self-designed device and used for bacteriophage 
      inactivation in water. Scanning electron microscope (SEM) and X-ray diffraction 
      (XRD) showed that the as-prepared Fe/Ni particles were spherical and the average 
      particle size was 93 nm. The synthesized Fe/Ni NPs achieved much higher removal 
      efficiency of bacteriophage f2 than nanoscale zero-valent iron (nZVI), while Ni 
      nanoparticles (Ni NPs) showed no removal effect on the bacteriophage f2. The 
      highest removal efficiency of bacteriophage f2 by Fe/Ni NPs was obtained when the 
      primary ratio of Fe:Ni was 5:1. In addition, the removal efficiency of phage f2 
      under aerobic condition was significantly higher than that under anaerobic 
      condition with Fe/Ni NPs, and the role of Ni was proved as a catalyst in the 
      system. Besides, the effect of initial pH, initial concentration of bacteriophage 
      f2, particles dose, rotation rate, and temperature on the removal efficiency of 
      bacteriophage f2 were studied. The result showed that the removal efficiency of 
      bacteriophage f2 did not change obviously in the test pH range (5-8), and was 
      positively related with the rotation rate and negatively related with the initial 
      concentration of bacteriophage f2. The particles dose could increase the removal 
      efficiency of phage f2, but the removal efficiency would decrease when the dose 
      was too much due to the aggregation of nanoparticles. The increase of temperature 
      could increase the removal efficiency initially, but decrease the removal 
      efficiency finally due to the accelerated corrosion of iron.
