Research Abstract

Soluble composite particles consisting of conducting polymer and steric stabilizer were prepared, and their stabilities and ion exchange properties were studied as inteligent ion exchanger. The dispersions of the polypyrrole-based composites were more stable than those for the polyaniline-based ones but extracted organic molecules less rapidly and quantitatively. However, epr investigation indicated that the polypyrrole composites had substantially greater numbers of cationic sites than the polyaniline composites at pH higher than 6.
1) Studies on ion exchange characteristics. The exchange selectivity for inorganic substrates increased in the sequence of C1 <Br <BF_4 <CIO_4 <SCN for the colloids. In the case of uptake of organic anions, dopant worked as a template for size recognition and the uptake was strongly dependent on the size of the dopant. Anionic molecules such as quinone sulfonates, and chromotripic acid were taken up into the colloids quantitatively. These injected molecules could be ejected completely on reducing the colloids both chemically and electrochemically.
2) Enantiodiscrimination of amino acid was attempted by using a polypyrrole- poly(vinyl alcohol) composite doped with N-carbobenzoxy-L-aspartic acid as a chiral selector. An enancio-excess ratio of 6 was obtained for uptake of 0.1 mM glutamic acid.
