Abstract
The ability of zirconium diphosphate (ZrP2O7) functionalized with oxalic acid to retain Europium (III) in solution has been studied. Zirconium diphosphate was synthetized and characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM-EDAX), Infrared Spectrometry (IR) and Atomic Force Microscopy (AFM) techniques, in order to determine its composition and purity. In order to understand the interaction between zirconium diphosphate and Eu (III), surface characteristic such as zero charge point (pHPCN) and surface site density (DS) were determined. Results from batch experiments showed that sorption capacity of zirconium diphosphate vis-a-vis Eu (III) was enhanced in the presence of oxalate ligand.
