Development of functional resins by modification of ion - exchange resins and their application to analytical chemistry

Some novel functional resins were developed for highly selective separation and/or determination of mercury, selenium, fluoride and hydrogen peroxide, by simple modification of common ion—exchange resin with appropriate reagents. These reagents should have three functional properties, namely selective reaction with the determinant of interest, an ion—exchange reaction with the resin and physical adsorption on the ion—exchange resin matrix. These functional resins were applied to the analysis of some environmental water samples and satisfactory results were obtained.
