摘要
Polymeric-coated magnetite particles with an adsorbed layer of extractant have been synthesized and are being evaluated for application in the separation and recovery of low concentrations of europium from water solutions. Physical characterizations of the extractant adsorbed particles were performed by X-ray diffractometry, Scanning Electron Microscopy and FT-IR spectrometry. Metal separations have been performed at various HNO(3) concentrations. Separation efficiency of the polymeric magnetic particles and the equilibrium adsorption isotherm of europium were investigated. Moreover, the magnetic field effect in the separation using a magnet was also verified. (C) 2002 Elsevier Science B.V. All rights reserved.
