Strongly Acidic Cation Exchange Resins

These resins have a crosslinked polystyrene matrix with sulfonic acid groups. Available grades include gel type (SK series), porous type (PK series), and highly porous type (HPK25). Standard shipping form is sodium salt, with hydrogen form sometimes available.

Example Grades and Properties (SK Series):

SK1B is a premium grade recommended for industrial softening and demineralization. SK110 and SK112 offer better performance in the presence of oxidizing substances due to higher crosslinkage. SK104H, with low crosslinkage, is used as a catalyst and for applications requiring penetration of large organic molecules or faster reaction rates.

PK Series (Porous Type):

PK216 is recommended for general water treatment. PK228 is recommended for condensate demineralization. PK grades are also used for deashing, decolorization, and as catalysts.

RCP160M (Highly Porous Type): Has higher porous properties than the PK series and is used for non-aqueous catalytic reactions or cation removal from non-polar solvents.

Strongly Basic Anion Exchange Resins

These resins feature a crosslinked polystyrene matrix with quaternary ammonium groups (NR₃⁺). They are available as gel-type (SA grades), porous-type (PA grades), and highly porous-type (HPA grades). The standard shipping form is Cl⁻ form, with OH⁻ form sometimes available.

• Type I resins have trimethyl ammonium groups, offering higher basicity, lower silica leakage in co-current regeneration, and better chemical stability for higher temperature applications.
• Type II resins have dimethylethanolamine groups, providing easier regeneration and slightly higher capacity.

Example Grades and Properties:

PA308 is used for demineralization and decolorization of sugar liquors. PA312 and PA316 are used in wastewater treatments. SA10A and SA12A are popular for water treatment. SA12A is recommended for surface waters with organic content. SA11A is used for special applications like mixed beds. SA20A is popular for water treatment due to ease of regeneration. HPA25L is a highly porous Type I resin for treating large molecules, enzyme purification, and high color value feed solutions. PA408 is used for demineralizing and decolorizing sugar liquors. PA418 is generally used in water treatment.

Cation Exchange Resins for Industrial Chromatography

DIAION™ UBK500 series are cation exchange resins for chromatographical separation.

Chelating Resins

These resins capture metal ions by chelation.

• CR11 (Iminodiacetate Type): Based on a high porous styrenic matrix. Captures metal ions by chelation with iminodiacetate functionality. Has high selectivity for divalent ions, especially transition metals, and can capture metal ions at lower pH than strong/weak acid resins.
• CR20 (Polyamine Type): Special chelating resin with polyamine functionality. Captures heavy metal ions with high selectivity and does not absorb alkali or alkali earth metal ions. Used for heavy metal recovery from alkali or alkali earth metal ion solutions.
• CRB03, CRB05 (Glucamine Type): Special chelating resins with glucamine groups on a high porous styrene/DVB matrix. High selectivity for borate ions, used for borate separation from brines and seawater.

Low-odor and Low-leachable Anion Exchange Resins

These resins suppress the leaching of TOC and amines and are used in drinking water manufacturing and sugar liquor refining.

Synthetic Adsorbents

These are used in refining pharmaceuticals and natural extracts.

• SP825L, SP850 (Aromatic Type): High porous, styrenic adsorbents with larger surface area and narrower pore-size distribution than HP20 grades. Offer twice the surface area or capacity for small molecules (< 1500 mw). Recommended for adsorption, desalting, and decolorization.
• SP70 (Aromatic Type): Moderate micropore sizes, adapted to US FDA standard, CFR §173.65.
• SP207 (Modified Aromatic Type): Higher hydrophobicity and greater selectivity for non-polar molecules due to chemically bonded bromine. Suitable for upward flow and batch processes due to high specific gravity.
• HP2MGL (Methacrylic Type): High porous, methacrylate-based adsorption resin, synthesized without aromatic compounds. Intermediate polarity, suitable for desalting and adsorption of relatively high polarity organic compounds.

Synthetic Resins of Small Particle Size for Chromatographical Separation

These resins are used for chromatographical separation in pharmaceuticals, fermentation, and food fields. Smaller particles with uniform size distribution yield higher purity and yields.

• HP20SS, SP20SS (Aromatic Type): Directly polymerized, small particle size versions of HP20. Offer excellent kinetics and capacity for small biomolecules and have been applied in simulated moving bed (SMB) applications.

Remarks in Handling Ion Exchange Resins

Handling: Wear protective equipment, handle in well-ventilated areas. Avoid contact with oxidizing agents, as resins may explode. Storage: Store in cool, dry, well-ventilated, dark places. Keep containers tightly closed. Avoid high temperatures and freezing conditions. Disposal: Dispose of unused resins according to regulations. Used resins adsorbing heavy metals must be handled according to waste disposal laws. Preparation before Use: Backwashing and conditioning (with dilute acid/alkali or regenerating reagents) are recommended for new resins to remove impurities. Consult with column designers for specific methods. Special preparations are available for ultrapure and beverage water applications.
