Abstract:
Zirconium phosphate (ZrP) is synthesized and characterized by X-ray diffraction (XRD), Scanning Electron Microscopy (SEM), Thermo Gravimetric Analysis (TGA) as well as pH titration experiments. A distribution coefficient (Kd) at different trace elements for pH value of 4 and at different pH was calculated experimentally. Also the Kd of strontium at different shaking times was calculated. Stability of inorganic ion exchanger at different pH was investigated too. The results show that ZrP is almost stability in acid medium, especially with the lower molarity. Also titration shows a that it has high ability of displacement of ions previously attached and loosely incorporated into its structure by oppositely charged ions present in the surrounding solution. In pH value of 4, ZrP is an useful inorganic ion exchanger and shows a high affinity for some elements such as Cs and Sr. The degree of ionization of ZrP depends on acid strength of solution. So when the pH drops, the capacity and Kd values fall off. In conclusion ZrP ion exchanger was found to have very good ion exchange capacity and high distribution coefficient for some elements. Also ZrP is a good inorganic ion exchanger for separation of strontium from other elements.
