Interaction of Heavy Metal Ions with Carbon and Iron Based Particles

Abstract

Due to the rapid development of industry and associated production of toxic waste, especially heavy metals, there is a great interest to create and upgrade new sorption materials to remove these pollutants from the environment. This study is aimed to determine the effectiveness of different carbon forms (graphene, expanded carbon, multi-wall nanotubes) and paramagnetic particles (Fe2O3) for adsorption of cadmium(II), lead(II), and copper(II) on its surface, with different interaction time from 1 minute to 24 hours. The main attention is paid to the detection of these metals using differential pulse voltammetry. Based on the obtained results, the graphene and Fe2O3 are found to be the good candidates for removal of heavy metals from the environment.
