Synthesis and Characterization of Sodium Dodecyl Sulphate Intercalated Zirconium Phosphate (SDS-ZrP): A New Zinc Selective Ion- exchange Material
Arshid Bashir and Altaf Hussain Pandith
Herein, we report the synthesis of surfactant based sodium dodecyl sulphate zirconium phosphate (SDS-ZrP) intercalated cation exchange material. The material was characterized by Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy(SEM), powder X-ray diffraction(XRD), thermo gravimetric analysis(TGA) and differential thermal gravimetry (DTG). The synthesized composite material showed good ion exchange capacity of 3.11 mequiv g-1 for strontium ion. Ion-exchange studies on the synthesized material have also been performed for heavy metal ions in neutral and acidic media .The composite exhibited high selectivity towards Zn (II) with distribution coefficient value of 4900mLg^(-1). The presence of surfactant in the matrix of composite highly enhances its adsorption capacity towards heavy metal ions. On the basis of significant dimensionless separation factor (SF) in a particular media, some binary separations of Zn (II) ion from other heavy metal ions were performed on the column loaded with SDS-ZrP.
