Synthesis and characterization of Nano particles of zero-valent iron for environmental remediation

Abstract

Nanoparticles of ZVI are the first field application of free released nanoparticles for environmental remediation. Nanoparticles of zerovalent iron have larger surface area and reactivity than normal zerovalent iron particles. A laboratory experiment was conduct to synthesize of nanoparticles of zerovalent iron. The 0.1M FeSO4 and 0.05M EDTA was mixed in a two necked flask by using propeller mixing. The 0.75M NaBH4 was added drop wise into the mixture solution. Slowly the solution turned to black colour. FTIR, TEM, SEM, DLS, DLS zeta, XRD and BET techniques were used to characterization of nanoparticles of zerovalen iron. In present study we synthesized nZVI with
