CHARACTERIZATION AND TESTING OF THE MAGHEMITE NANOPARTICLES USED FOR REMOVAL OF HEXAVALENT CHROMIUM FROM AQUEOUS SYNTHETIC SOLUTIONS Autori: Andra Mihaela Predescu, Andrei Predescu, , Eugeniu VasileData aparitiei: November/2011 Revista: Environmental Engineering and Management Journal › Vol. 10 › Nr. 11 ISSN: 1843 - 3707 ![]() Abstract:
The paper refers at adsorption studies using the maghemite nanoparticles as adsorbent for removal of the hexavalent chromium from aqueous synthetic solutions. Adsorption reached at equilibrium within 10 minutes and was registered as maximum at pH 2.54. The adsorption data were analyzed and fitted by Langmuir isotherm. Investigation methods for characterization of the nanoparticles were X-ray diffraction, scanning and transmission electron microscopy. Also, in order to evaluate the hexavalent chromium concentration the atomic and molecular absorption spectrometry were used. |
