Synthesis and Characterisation of Zirconium Phosphate Ion Exchanger and its Composites

Abstract

Zirconium Phosphate (ZrP) as an ion exchanger was synthesized and modified with CNTs and incorporated in the framework of ZrP. The CNTs were used in modification of ion exchanger. The ion exchange capacity was determined in each ion exchanger and the ion exchange capacity of modified ZrP was much higher than ZrP. Moreover, characterization of both the ion exchangers were studied such as, X-Ray Diffraction, Scanning electron microsope, Solubility, Kinetics. The X-Ray diffraction results show the amorphous character of both the samples. The chemical stability was observed in various solvents and found that ZrP-CNT has good chemical stability in acids, salt solutionsand in various bases. Ion exchangers have a good kinetic behavior with the three different metals, with CNT as comparative to without CNT zirconium phosphate. The size, shape and morphology were studied using scanning electron microscope. The ion exchange capacity of modified ion exchanger was improved by 36% than that of its classical analogue.
