Amphoteric Ion-Exchange Resin DIAION? series

DIAIONTM AMP03 is an amphoteric ion-exchange resin with a quaternary ammonium group and carboxy group incorporated into the crosslinked polystyrene backbone. Thanks to uniform 260 µm beads size, AMP03 realizes sharp elution peak in the separation of electrolytes from non-electrolytes, between electrolytes(sodium chloride and sodium sulfate), etc.

Amphoteric Ion-Exchange Resin DIAION™ series

DIAIONTM AMP03 is an amphoteric ion-exchange resin with a quaternary ammonium group and carboxy group incorporated into the crosslinked polystyrene backbone. Thanks to uniform 260 µm beads size, AMP03 realizes sharp elution peak in the separation of electrolytes from non-electrolytes, between electrolytes(sodium chloride and sodium sulfate), etc.

Characteristics

DIAIONTM AMP03 is an amphoteric ion-exchange resin newly developed by Mitsubishi Chemical. Amphoteric ion-exchange resins are characteristically able to retain salts using only water as the medium, making them suitable for the separation of electrolytes from non-electrolytes, between electrolytes(sodium chloride and sodium sulfate), etc.

DIAIONTM AMP03 has a structure in which functional groups with equivalent positive and negative charges are fixed to the crosslinked polystyrene matrix by stable chemical bonding, achieving an outstanding design with little deterioration over time and elution.

As particles have a uniform size of 260 µm, elution peak is sharp, making it best suited for industrial separation and refinement.

DIAIONTM AMP03 is able to differentiate and identify various salts using only water as the developing solvent(mobile phase).

Selectivity has the following tendencies:

The greater the cation valence, the larger the retentive force.

The greater the anion valence, the smaller the retentive force.

The following diagram shows the retentive values obtained by filling DIAIONTM AMP03 into the column and developing various salts.

Applications

Useful for the desalination of sugar liquids, separation of electrolytes from non-electrolytes such as glycerin from salt, and mutual separation of electrolytes such as caustic soda and salt. Please visit the DIAION website for examples of separation using amphoteric ion-exchange resin.

■Method of use

Liquid passage through column or liquid batch process
