Strongly Acidic Cation Exchange Resins DIAION? sereies

The strongly acidic cation exchange resins are bead-like products which have a sulfonic acid group in the cross-linked styrene frame. They can be used across the full pH range(0-14), and are relatively stable to temperature, even withstanding high temperatures of 100-120℃. They are used in a wide variety of fields including water purification, water softening, wastewater treatment, purification of pharmaceuticals and food, and catalysis.

Strongly Acidic Cation Exchange Resins DIAION™ sereies

The strongly acidic cation exchange resins are bead-like products which have a sulfonic acid group in the cross-linked styrene frame. They can be used across the full pH range(0-14), and are relatively stable to temperature, even withstanding high temperatures of 100-120℃. They are used in a wide variety of fields including water purification, water softening, wastewater treatment, purification of pharmaceuticals and food, and catalysis.

Characteristics

The strongly acidic cation exchange resins are bead-like products which have a sulfonic acid group in the cross-linked styrene frame.

Greenherbs

The sulfonic acid group(-HSO3) is the exchange group and behaves like a strong acid, dissociating to(-SO3)- and H+ even in acidic solutions, not to mention in alkaline solutions.

There are a gel type(SK series), a porous type(PK series), and a uniform bead size type(UBK series).

■ Characteristics

An ion exchange reaction is simply a pair of ions changing places. The reactions shown below illustrate this process for a strongly acidic cation exchange resin. Salts such as NaCl and CaCl2 or a base such as NaOH can undergo the ion exchange reaction when exposed to the resin in solution.

R-SO3H +NaCl → R-SO3Na +HCl

2R-SO3H +CaCl2 → (R-SO3)2Ca +2HCl

R-SO3H +NaOH →R-SO3Na +H2O

(R represents the ion exchange resin matrix.)

Although the strongly acidic cation exchange resin adsorbs all positive ions, the adsorption strength depends on the type of ion. The index of this strength is called selectivity. In general, selectivity will increase as the ion valence increases. (For example, Na+ <Ca++ <Al+++ <Th++++.) For the same valence, selectivity increases as atomic number increases.(Li+ <Na+ <K+ <Rb+ <Cs+, Mg++ <Ca++ <Sr++ <Ba++)

These DIAION™Series resins can be used across the full pH range(0-14), and are relatively stable to temperature, even withstanding high temperatures of 100-120℃.

Applications

They are used in a wide variety of fields including water purification, water softening, wastewater treatment, purification of pharmaceuticals and food, as well as catalysis.

■Usage

Packed column or Batch processing

Lineup / Specifications

Mitsubishi Chemical's Strongly Acidic Cation Exchange Resins are listed below.

SK Series(Gel Type)

SK1B has a standard level of cross-linking and is widely used. If the incoming raw water contains an oxidizing agent, irreversible swelling is a concern, and SK110 or SK112 with higher degrees of cross-linking than SK1B are recommended.

SK104 has a low degree of cross-linking and is suitable for applications that require high reaction rate such as catalysis.

UBK Series(Gel Type, Uniform Bead Size)

In recent years, various improvements in water purification equipment combined with uniform bead diameter resin have enabled reduction of chemical costs and reduction in required resin regeneration solution volumes. Also in applications beyond water purification, the many advantages of uniform bead size have increasingly made their use a necessity. One advantage is that there are no large-diameter beads that are prone to breakage due to swelling and contraction.

According to this growing need, we have made uniform bead size available for the most widely used general purpose ion exchange resins.

PK Series(Porous Type)

This is a porous product in which the matrix itself is porous, yet is highly durable with swelling and contraction. PK212 or PK216 are used for general-purpose water treatment, while PK228 is used for condensate desalination. In addition, this type is used as a catalyst, because it provides high reaction rate, especially in organic solvents.

UBK500 Series for Chromatographic Separation

Chromatographic separation technology is widely implemented for industrial-scale processing in the pharmaceutical, fermentation, and food fields. In this processing, ion exchange resins with small bead size and uniform bead size are used.

DIAION™ UBK500 Series is a uniform, small-diameter cationic exchange resin. Two kinds are available --- the Na type and the Ca type.
