Outline of Final Research Achievements

The cross-linking degree of an ion exchange resin determined the independency of the space usable for ion exchange in the resin phase, and eventually provided significant differences in the exchange kinetics, the saturated relative exchange, and the dependency of the selectivity on the relative exchange. The retention of an organic compound to an ODS-silica was attributed to the sum of the distribution and the adsorption, and the importance of the residual silanol group was pointed out with respect to the wettability. The ion exchange of triphosphate was achieved by use of a Zr-porphyrin complex, and its reaction product showed an intermolecular interaction contributing to the high selectivity. The ion exchange resin with a low capacity provided no practical ion exchange due to reduction of the wettability.
