List of Cation exchange resins

Cation exchange resins are used in medicine to remove an excess of a particular positively charged ion that has accumulated in the body. When the resin is administered to the patient the positively charged ions binds to the resin in an exchange for another positive ion.

Ion exchange resins as drug delivery carriers

An ion exchange resin is exhibited like small bead with a diameter between 12 mm. It is usually white or yellowish and it is fabricated from an organic polymer substrate backbone. Ion exchange is a reversible process in which ions of like sign are exchanged between liquid and solid when in contact with a highly insoluble

The Role of Crosslinking in Ion Exchange Resins WCP Online

The sulfonation process renders the styrene largely water soluble and it swells with water and provides the active exchange site for ion exchange to take place. If the resin is in the hydrogen form, it serves as part of a de ionization system by removing all of the cationic ( positive charge ) ions from the feed stream, replacing them with H+.

Other articles where Cationexchange resin is discussed: separation and purification: Chromatography: In a cationexchange resin all the sites are negatively charged, so that only positive ions can be separated; an anionexchange resin has positively charged sites. Ionexchange chromatography has become one of the most important methods for separating proteins and small oligonucleotides.

The total 14 C content and its speciation (inorganic/organic) were measured in spent ion exchange resins (SIERs) received from Cernavoda Nuclear Power Plant (NPP). Also, 14 C release from SIERs was investigated by desorption tests carried out in alkaline solution relevant for cementitious environment disposal. The method used for total 14 C measurement consists of combustion in oxygenrich ...
