The Strong Base Anion Exchange Resin 201X4 FG is a high-performance, premium-grade ion exchange medium engineered for precision separation and purification. Utilizing a gel polystyrene structure crosslinked with divinylbenzene, this resin features quaternary ammonium functional groups in the chloride (Cl-) form, ensuring exceptional selectivity and high exchange capacity for demanding industrial applications.
Specifically designed for versatility, this resin excels in water treatment, the production of high-purity water, and the specialized extraction of antibiotics. By combining rigorous quality control with a stable polymer matrix, the 201X4 FG offers a reliable solution for enterprises seeking to optimize their ion removal processes and achieve superior effluent quality in compliance with global industrial standards.
| Appearance | White to pale yellow clear spherical beads | Polymer Structure | Gel polystyrene crosslinked with DVB |
|---|---|---|---|
| Functional Group | -N(CH3)3 | Ionic Form | Cl- (as shipped) |
| Weight Exchange Capacity | ≥3.7mmol/g | Volume Exchange Capacity | ≥1.10mmol/ml |
| Real Density | 1.06-1.10g/ml | Bulk Density | 0.66~0.71g/ml |
| Particle Size Range | 0.315~1.25 mm (≥95%) | Uniformity Coefficient | ≤1.6 |
Optimized for purity water preparation and antibiotic extraction with minimal color throw (≤25 APHA).
Capable of maintaining structural integrity and performance at maximum operating temperatures up to 100℃.
High exchange capacity (≥1.10mmol/ml) ensures efficient ion removal and reduced regeneration frequency.
With a uniformity coefficient ≤1.6, it prevents channeling and ensures optimal flow distribution.
High whole bead count (≥95%) minimizes fines and reduces pressure drop across the resin bed.
Directly comparable in performance to leading brands like Amberlite IRA-401 and Diaion SA.
Implement flocculation and sand filtration to prevent suspended solids from jamming resin pores.
Maintain operating velocities between 2-10 BV/h and column diameter ratios within reasonable ranges.
Utilize a precise alkali-water-acid-water flow path with 3%-5% HCl and 2%-4% NaOH.
Account for transformation expansion rates to prevent resin overflow and ensure stable liquid levels.
Keep resins in a wet state above 0℃; use 5% salt water for long-term preservation.
Use wet packing or back-flushing techniques to eliminate internal bubbles within the resin layer.
| Feature | Standard Resins | 201X4 FG Resin |
|---|---|---|
| Exchange Capacity | Moderate (Low mmol/ml) | High (≥1.10 mmol/ml) |
| Operational Life | Standard degradation rate | Extended due to High Whole Bead Count |
| Process Efficiency | Higher pressure drops | Optimized Flow (Low Uniformity Coeff) |
| Regeneration Cost | Frequent regeneration needed | Reduced cycles via high capacity |
| Water Purity | Basic ion removal | Ultra-pure grade (APHA ≤25) |
This resin is primarily used for water treatment, the production of high-purity water, and the specialized extraction of antibiotics in the pharmaceutical industry.
Resin should be kept in a wet state in a closed space. For long-term storage, it is recommended to add a 5% or higher salt water solution and maintain temperatures above 0℃ to prevent freezing.
The recommended regeneration agents are 2BV of 3%~5% HCl followed by 2BV of 2%~4% NaOH to restore the resin's exchange capacity.
Steps such as flocculation, filtration, or sand-filtration are essential to remove suspended solids, which would otherwise jam the resin pores and reduce efficiency.
The 201X4 FG resin is designed to operate effectively at a maximum temperature of 100℃.
Regular backwashing is recommended to loosen the resin, or the resin should be stored outside the column in a salt-resistant medium after washing.
