Abstract Scope Iron nanoparticles exhibit interesting properties that can be exploited in a variety of applications such as mitigation of wastewaters. For the development of this project a typical cell of three electrodes was used, an iron working electrode was used against a ruthenium oxide mesh as dimensional stable anode and as reference electrode a saturated calomel electrode. The electrochemical techniques used were: cyclic voltammetry, chronopotentiometry and galvanostatic pulses. The characterization of the solution treated by the galvanostatic pulses technique was performed by UV-Vis, where it was possible to observe the characteristic band of iron nanoparticles. The materials deposited on the electrode were caracterized by SEM-EDS to observe the size of the particles obtained by the cronopotentiometrys. To study the affinity of the iron nanoparticles on heavy metals, a solution containing arsenic was prepared; the reduction of arsenic was studied by AAS, calculating the concentration of arsenic ions contained in the solution.
