Lead is one of heavy metals.This toxic metal  has more application in several industry for example, battery manufacture ,tetraethyl lead manufacture , armament, paint    manufacture. This wastewaters are more toxic and  they vacate  are more hazardous for environment ,in this paper benefical of magnetite iron nano particles  pollution of lead  decreased up to standard (0.5ppm)andby alteration of chemical and phisycal parameters determined foremost term for adsorption of lead  namely, PH, concentration of magnetite iron nano particles, temperature and designed freundlich and langmuir  diagrams . at the end showed  diagram industrial application .result of this research detect high removal percent of lead(70%) in the PH =5.5-6.
