Abstract
- ABSTRACT Organic-inorganic nanocomposites poly- o-anisidine and poly- o-toluidine Sn(IV) tungstate were chemically synthesized by mixing organic polymers that is, o-anisidine and o-toluidine with inorganic gels of Sn(IV) tungstate in different mixing ratios. Ion-exchange kinetics for few divalent metal ions was evaluated by particle diffusion-controlled ion-exchange phenomenon at four different temperatures. The particle diffusion mechanism was confirmed by linear τ (dimensionless time parameter) versus t (time) plots. The exchange processes were controlled by the diffusion of ions within the exchanger particle for the systems under studies. Some physical parameters such as self-diffusion coefficient ( [ABSTRACT FROM AUTHOR]
