Latha Raj 1 Department of Chemistry, Govt. Engineering College, Thrissur, Keral - 680 009 (INDIA) <p>Studies on the synthesis, composition and ion exchange properties of Bismuth (III) iodoantimonate have been carried out. This exchanger is stable in water, ethanol, acetic acid, HCl (2m), HNO<sub>3</sub> (2m), H<sub>2</sub>SO<sub>4</sub> (2m), NH<sub>4</sub>No<sub>3 </sub>(1M) and in solutions of LiCl, NaCl, KCl, BaCl<sub>2</sub>, SrCl<sub>2</sub> and Mg SO<sub>4</sub>. it can be regenerated twice without any appreciable decrease in the ion exchange capacity. The empirical formula proposed is &frac12; Bi<sub>2</sub>O<sub>3</sub>. &frac12; I<sub>2 </sub>O<sub>5</sub>. &frac12; Sb<sub>2</sub>O<sub>3</sub>. 3H<sub>2</sub>O or Bi<sub>2</sub>O<sub>3</sub>. I<sub>2</sub>O<sub>5</sub> . Sb<sub>2</sub>O<sub>3</sub>. 6 H<sub>2</sub>O. Bi : I : Sb ratio was calculated from titrimetric and gravimetric analysis. Bismuth (III) iodoantimonate shows high affinity for Pb (II), Cd (II), Cu (II), CO (II) and Ni(II). Five binary separations ranging from 96 to 98% have been achieved on Bismuth (III) iodoantimonate columns.</p> https://journalofchemistry.org/paper/611/ iodoantimonate columns
