Abstract

New lower rim modified phosphorylated thiacalix[6]arene derivative such as TC6A-phosphate (2) was synthesized. IR, 1H & 31P NMR and mass spectral and elemental analysis characterized the structure of the synthesized compound. We also investigated the metal extraction ability of the newly synthesized compound through solvent extraction technique from automotive catalyst residue, standard mixed metal, standard Pd and Zr solutions. This compound showed high selectivity towards Zr and Pd ions.
