Abstract
We have investigated the removal of Pb2+ ions from water using thiolfunctionalized cobaltferrite magnetic nanoparticles These magnetic nanoparticles were prepared using the coprecipitation method and their surfaces were modified with tetraethoxy silane and 3mercaptopropyl trimethoxysilane in order to provide a sufficient surface concentration of the thiol –SH functional groups The adsorption of the Pb2+ ions from the aqueous solutions onto the thiolfunctionalized cobaltferrite magnetic nanoparticles was studied The investigated parameters include the pH value of the model water the concentration of the adsorbent the contact time and the temperature of adsorption The removal of the Pb2+ was found to be greater at the higher pH values and increasing the temperature was also found to increase the removal of Pb2+ ions“Operation part financed by the European Union European Social Fund Operation implemented in the framework of the Operational Programme for Human Resources Development for the Period 2007–2013 Priority axis 1 promoting entrepreneurship and adaptability Main type of activity 11 experts and researchers for competitive enterprises”
