Abstract: A chromatograhically useful packing material has been prepared by the adsorption of Alizarin Red-S on cation exchanger stannic silicate. Adsorption behaviour of some transition and heavy metals on Alizarin Red-S loaded stannic silicate has been studied in aqueous solutions of <i style="">p</i>H 1-6. This material has been used for the selective separation of Cd<sup>2+</sup> and Pb<sup>2+</sup> from a mixture of several cations, viz. Cr<sup>3+</sup>, Hg<sup>2+</sup>, Fe<sup>3+</sup>, Co<sup>2+</sup> and Ni<sup>2+</sup><sup> </sup>using nitric acid solution of <i style="">p</i>H 1 and 6 as eluents. In addition, some binary separations of metal ions, namely Zn<sup>2+</sup> - Cd<sup>2+</sup>, Mn<sup>2+</sup> - Cd<sup>2+ </sup>, Hg<sup>2+</sup> - Cd<sup>2+</sup>, Al<sup>3+</sup> - Pb<sup>2+</sup> and Cr<sup>3+</sup> - Pb<sup>2+</sup> have also been achieved on a chromatographic column packed with Alizarin Red-S loaded stannic<b> </b>silicate.
