In this research work, we provided a method to remove the lead ion(Pb2+) from industrial wastewater. Nanoscale zero-valent iron (nZVI) has high specific surface area, high reductive ability and high reactive velocity than other absorbents was used to remove Pb2+ in this experiment. Firstly, we use the different concentration of nZVI (0.1, 0.2, 0.3, 0.4, 0.5 g/L) mixed in to the water which contained Pb2+ with different temperature (15, 20, 25, 30, 35 ℃). Secondly, we fixed the temperature of solution but different Pb2+concentration. Through this experiment we not only can observe nZVI’s properties, but also obtain an advantage effect of Pb2+ adsorption.
