Synthesis and Thermal Studies of Polyaniline Stannic Silicate and Its Role in the Removal of Toxic Metal Ions

A composite ion exchange material, polyaniline stannic silicate was prepared under different experimental conditions. Ion exchange material synthesized at pH 1.0 shows an ion exchange capacity 1.6 meq/g for Na+ ions. The exchanger has been characterized on the basis of X-ray and TGA. Ion exchange capacity, pH titration, elution and distribution studies were also carried out to determine the preliminary ion exchange properties of the material. The effect of temperature on the ion exchange capacity of the material at different temperatures has been studied. The sorption behavior of metal ions was also explored in different surfactant mediums. The practical utility of the material was explored by achieving quantitative separation of toxic metal ions in synthetic mixtures.
