Newly developed organic–inorganic cation-exchange materials poly-o-anisidine and poly-o-toluidine Sn(IV) tungstate composites were synthesized by a modified sol–gel technique by incorporating Sn(IV) tungstate precipitate with the matrix of electrical conducting poly-o-anisidine and poly-o-toluidine. The materials showed good ion-exchange behavior and were used successfully in the separation of metal ions. The conductivity of the composites was measured by 4-in-line-probe DC electrical conductivity measuring device and was found within the range of 10−4–10−2 S/cm. The DC electrical conductivity of both composite materials was found stable up to 140 °C under ambient conditions. The conductivity was at the border of metallic and semiconductor region.
