AmberLite XAD 16N

Summary

Product identification

• Product Name: AmberLite™ XAD™ 16N Polymeric Adsorbent
• Type: Macroporous, Adsorbent Resin
• Manufacturer: DuPont
• Form No.: 45-D01962-en, Rev. 3
• Date: May 2020

Description

AmberLite™ XAD™ 16N is a nonionic, hydrophobic, crosslinked polymer supplied as white, insoluble beads. It functions as a macroporous adsorbent with a high surface area and aromatic surface. It is designed to adsorb hydrophobic molecules from polar solvents and volatile organic compounds from vapor streams. Its pore size distribution is suitable for adsorbing organic substances of relatively low to medium molecular weight. It can be used in column or batch operations.

Applications

• Recovery and purification of antibiotics, water-soluble steroids, enzymes, amino acids, and proteins.
• Removal of non-polar compounds, such as phenol, from polar solvents.

• Elution/Desorption: 1 – 4 BV/h
• Regeneration: 1 – 4 BV/h
• Rinse: 2 – 16 BV/h * 1 BV (Bed Volume) = 1 m³ solution per m³ resin or 7.5 gal per ft³ resin

Regenerants or Eluting Agents

• Water-miscible organic solvents (methanol, ethanol, isopropanol, acetone, etc.) for hydrophobic compounds
• Pure solvents for regenerating resin fouled by oils and antifoams
• Dilute bases (0.1 – 0.5% NaOH) for eluting weakly acidic compounds
• Concentrated bases (2 – 4% NaOH) for regenerating resins fouled with proteins, peptides
• Dilute acids (0.1 – 0.5% HCl) for weakly basic compounds
• Dilute oxidizing agents (< 0.5%) such as peroxide to enhance the removal of protein fouling
• Buffer elution for pH-sensitive compounds
• Water when adsorption is from an ionic solution
• Hot nitrogen or steam for volatile materials

Hydraulic Characteristics

• Estimated bed expansion as a function of backwash flowrate and temperature is shown in Figure 4 (Temperature = 10 – 50°C).
• Estimated pressure drop as a function of service flowrate and water temperature is shown in Figure 5 (Temperature = 5 – 65°C). These expectations are valid at the start of a service run with clean feed and a well-classified bed.

Application Information

Pretreatment

AmberLite™ XAD™ 16N is shipped water-wet with sodium chloride (NaCl) and sodium carbonate (Na₂CO₃). These salts should be washed off by rinsing with water at a linear flowrate of 5 – 10 m/h until the required level is achieved. For sensitive applications, a regeneration with the proposed regenerant is recommended before the first service cycle. If an alcohol is used as the regenerant, it must be displaced with water before the first loading cycle.
