The role of ion-exchange resins (IERs) as catalysts or supports, in hydrogenation reactions is revised and their potential application presented. Both gel-type macroreticular, basic acid, IERs have been used for manifold metal-catalyzed processes gas liquid phase, including alkenes, alkynes, carbonyls, arenes, nitroaromatics, more. When available, qualitative relationships between the morpholog...

Surface and groundwater always contain hardness ions (Ca2+ Mg2+). The is an important characteristic that provides the consumer properties of water. This parameter must be taken into consideration by stations water treatment, thermal power plants, enterprises chemical, food, pharmaceutical industries. Ion exchange resins, which are intended for softening, considered in this chapter. negative ef...

A new approach to the separation of radiophosphorus from sulfur has been found which makes a unique use of ion exchange resins. Separations using resin columns are especially suited to problems involving radioactivity since they require a minimum of handling.

Pre-concentration of analytes, or matrix removal to overcome interferences using mini- or micro-columns of exchange media prior to atomic spectrometric detection is becoming increasingly more common. This paper is a review of some of the more recent applications of chelating, ion exchange and other resins and gels that have been used to accomplish this.
