Synthesis and ion exchange behaviour of polyaniline Sn(IV) arsenophosphate: a polymeric inorganic ion exchanger

摘要: Incorporation of a polymer material into an inorganic ion exchanger provides class hybrid exchangers with good exchange capacity, high stability, reproducibility and selectivity for heavy metals. Such type ‘polyaniline Sn(IV) arsenophosphate’ has been synthesized by mixing polyaniline material. This is characterized using X-ray, IR, TGA studies in addition to pH-titration, elution distribution behaviour. On the basis studies, found be highly selective Pb(II). Kinetic study metal ions performed some physical parameters such as self diffusion coefficient D0, energy Ea entropy ΔS* activation have determined.
