Abstract: The present study deals with adsorption and desorption of mercury on surface functionalized nanomagnetic particles. The nano-magnetic particles (Fe304) were synthesized by chemical precipitation of Fe2 and Fe3 salts at 80 o at alkaline condition and inert atmosphere. The particle surface was then functionalized in two different ways: surface charge controlled by solution pH and coating the surface with polymer (vinylpyrrolidone) with thiodiglycolic acid as the primary surfactant and 4-vinylaniline as the secondary surfactant. It was found that the adsorption of mercury was pH dependent and maximum adsorption occurred at pH of 7.5 with bare particles and at pH 10 for polymer grafted particles. Maximum adsorption of mercury was found to be 280 mg/g particle. Copyright © 2009 American Scientific Publishers All rights reserved.
