The Strong Base Anion Exchange Resin 201X8 FG is a high-performance, professional-grade ion exchange medium engineered specifically for the production of ultra-pure water and advanced wastewater treatment. Composed of a gel polystyrene structure crosslinked with divinylbenzene, this resin features quaternary ammonium functional groups in the chloride (Cl-) form, ensuring exceptional selectivity and efficiency in removing anionic impurities from aqueous solutions.
Designed to meet the rigorous demands of industrial water purification, the 201X8 FG offers a superior weight exchange capacity of ≥3.8mmol/g and a high volume exchange capacity of ≥1.5mmol/ml. Its precise particle size distribution and low uniformity coefficient make it an ideal choice for systems requiring consistent flow rates and minimal pressure drops, providing a reliable alternative to industry standards like Purolite A100.
| Appearance | White to pale yellow clear spherical beads | Polymer Structure | Gel polystyrene crosslinked with DVB |
|---|---|---|---|
| Functional Group | -N(CH3)3 | Ionic Form (as shipped) | Cl- |
| Weight Exchange Capacity | ≥3.8 mmol/g | Volume Exchange Capacity | ≥1.5 mmol/ml |
| Bulk Density | 0.66~0.71 g/ml | Water Retention Capacity | 43%~47% |
| Particle Size Range | 0.315~1.25 mm ≥95% | Uniformity Coefficient | ≤1.6 |
Exceptional capacity of ≥3.8mmol/g ensures longer run times between regeneration cycles.
Designed for resilience with a maximum operating temperature of up to 100℃.
High whole bead count (≥95%) reduces fines and prevents column clogging.
Optimized for ultra-pure water preparation and high-standard wastewater treatment.
Uniformity coefficient ≤1.6 ensures stable hydraulic flow and prevents channeling.
Fully compatible as a high-efficiency replacement for Purolite A100 systems.
Resin must be kept wet; recommended storage temperature is above 0℃ to maintain integrity.
Store in closed containers with 5% or higher salt water to prevent dehydration and degradation.
Utilize flocculation or sand-filtration before the resin column to prevent pore jamming by solids.
Standard processing requires an Alkali-Water-Acid-Water sequence for optimal performance.
Set aside adequate freeboard space based on transformation expansion rates to prevent overflow.
Maintain a reasonable column diameter ratio to avoid biased currents and ensure uniform flow.

| Operating Life | Standard | Extended / High-Durability |
| Regeneration Cost | Moderate | Optimized (Low chemical waste) |
| Water Purity Level | Basic Pure | Ultra-Pure Grade |
| Maintenance Cycle | Frequent | Reduced / Long-term |
The 201X8 FG resin is primarily used for the preparation of high-purity water and the treatment of industrial wastewater, specifically removing strong acid anions from solution.
Resin should be stored in a closed space. If unused for a long period, it is recommended to add a salt solution of 5% or higher and ensure it is kept above 0℃ to prevent freezing.
Regeneration typically involves using 2BV of 3~5% HCl followed by 2BV of 2~4% NaOH, depending on the specific application and purity requirements.
Steps such as flocculation, filtration, or sand-filtration are required to remove suspended solids that would otherwise jam the resin pores and reduce efficiency.
This resin is designed to withstand operating temperatures up to 100℃, making it suitable for various high-temperature industrial processes.
You must account for the different transformation expansion rates of the resin when designing the column, leaving sufficient headspace to prevent overflow during backwash.
