your question is too vauge for a proper response. ion exchange resins are designed for a specific purpose....to take out minerals, acids, color, etc.....
also the charge of the media being anion or cation and the form.. cloride or hydroxide play a major part in picking a product for use...specify what you wish to accomplish with the resin. there are hundreds of resins.
Anion exchange chromatography separates molecules based on their negative charge, while cation exchange chromatography separates molecules based on their positive charge.
Cation exchange chromatography separates molecules based on their positive charge, while anion exchange chromatography separates molecules based on their negative charge.
Anion exchange chromatography and cation exchange chromatography are both types of ion exchange chromatography used to separate molecules based on their charge. The key difference between them is the type of ions they attract and retain. Anion exchange chromatography attracts and retains negatively charged ions (anions), while cation exchange chromatography attracts and retains positively charged ions (cations).
Cation exchange chromatography separates molecules based on their positive charge, while anion exchange chromatography separates molecules based on their negative charge. The key difference lies in the type of charge that is used to separate the molecules.

polyatomic anion
The anion in sulphates is the SO42-.
Cl -As this is a negatively charged ion it is a anion.
Anion
anion
The anion of chlorine is chloride (Cl-).
If Anion exchanger use before cation exchanger in water treatment system then following problem occured 1. Deposition of sulphate in bed at high pH. 2. Elimination of CO2 Gas will not possible at high pH. 3. Due to very high pH in Cation unit sludge will be form which is the cause of strainer chocking & effect to resin quality. 4. Increse possibility of sodium slippage.
