Column chromatography can be used, but solid-phase metal scavengers ( ion exchange resins and derivatives of silica gel ) promise more efficient separation.
22.
The most state-of-the-art facility in Asia for the production of ion exchange resins for water treatment was set up at the Jhagadia site in India.
23.
Certain ion exchange resins are also used pharmaceutically as bile acid sequestrants, mainly as hypolipidemic agents, although they may be used for purposes other than lowering cholesterol.
24.
In ex situ treatment via ion exchange, contaminants are attracted and adhere to the ion exchange resin because such resins and ions of contaminants have opposite charge.
25.
Styrene and divinylbenzene react to form the copolymer styrene-divinylbenzene, S-DVB or Sty-DVB . The resulting cross-linked polymer is mainly used for the production of ion exchange resin.
26.
Examples of functional groups of Weak ion exchange resins include diethylaminoethyl ( DEAE ), which is an anion exchanger, and carboxymethyl ( CM ), which is a cation exchanger.
27.
Ion exchange resins are organic polymers containing anionic functional groups to which the divalent cations ( Ca + + ) bind more strongly than monovalent cations ( Na + ).
28.
The compound reacts violently with water, yielding caesium hydroxide, metallic gold, and hydrogen gas; in liquid ammonia it can be reacted with a caesium-specific ion exchange resin to produce tetramethylammonium auride.
29.
Examples of functional groups of strong ion exchange resins are quaternary ammonium ( Q ), which is an anion exchanger, and sulfonic acid ( S ), which is a cation exchanger.
30.
During the same year, the group invested around EUR 30 million in a production facility for ion exchange resins for water treatment in the Gujarat region of India . [ 12]
