Polyethylene glycol-stabilized bimetallic nickel–zero valent iron nanoparticles for efficient removal of Cr(vi)

In order to solve the agglomeration of nanoscale zero-valent iron (nZVI) and improve its performance in pollutant treatment, polyethylene glycol-stabilized nickel modified nZVI (Ni/Fe–PEG) was synthesized by a liquid-phase reduction method and used to treat Cr(vi) solution for the first time.
