Pollution of toxic heavy metals and organic chemicals are most common environmental problem nowadays,for example,the bivalent cadmium(Cd(Ⅱ))and the parachloronitrobenzene.Hence the environment pollution caused by these two pollutants was a common problem all over the world and their removal was highlighted by many researchers.Zero velent Fe nanoparticles(ZVFeNPs)are one kind of potential reducer to eliminate the toxic pollutants,but the application was plagued by the aggregation-prone problem similar to other nanoparticles.
