The Strong Basic Anion Exchange Resin D201 MB is a high-performance, industrial-grade ion exchange medium designed for critical separation and purification processes. Engineered as opalescent to light gray opaque spherical beads, this resin delivers exceptional stability and efficiency in desalination and the adsorption of cyanide pulp, making it an essential component for advanced chemical processing and water treatment systems.
With a robust weight exchange capacity of ≥3.7mmol/g and a wide operational temperature range up to 120°C, the D201 MB is optimized for demanding environments. Its precise particle size distribution and high whole-bead count ensure minimal pressure drop and maximum kinetic efficiency, offering a professional-grade alternative to industry standards such as Amberlite 200, Lewatit Sp-210, and Diaion PA308.
| Ionic Form | Cl- | Weight Exchange Capacity | ≥3.7 mmol/g |

Capable of maintaining structural integrity and performance at temperatures reaching up to 120°C.
High exchange capacity (≥3.7mmol/g) ensures longer run times and reduced regeneration frequency.
A uniformity coefficient of ≤1.4 and ≥95% whole beads prevent clogging and optimize flow.
Highly effective for desalination and cyanide pulp adsorption in hydrometallurgy.
Optimized for operating velocities between 2-10 BV/h for balanced throughput and purity.
Directly compatible with systems designed for Amberlite 200 and Lewatit Sp-210.
Implements flocculation and sand-filtration to prevent suspended solids from jamming resin pores.
Follows a strict alkali-water-acid-water sequence to maximize ion exchange efficiency.
Calibrated expansion rate settings to prevent resin overflow and maintain liquid height.
Systematic desorption using 3-5% HCl and 2-4% NaOH for complete resin restoration.
Wet state preservation above 0°C with 5% salt water for long-term stability.
Strategic diameter ratio design to avoid bias currents and ensure uniform fluid distribution.

| Thermal Limit | 80 - 100°C | Up to 120°C |
| Bead Integrity | 85% - 90% Whole | ≥95% Whole |
| Operational Life | Standard Cycle | Extended (High Stability) |
| Regeneration Cost | Standard Reagent Use | Optimized (High Capacity) |
It is primarily used for water desalination and the adsorption of cyanide pulp in the hydrometallurgy industry.
Resin must be kept in a wet state at temperatures above 0°C. For long-term storage, keep it in a closed space or add a 5% or higher salt water solution.
The recommended regeneration process involves using 2BV of 3~5% HCl followed by 2BV of 2~4% NaOH.
Yes, the resin is designed to withstand maximum operating temperatures of up to 120°C.
It is critical to perform pre-treatment steps such as flocculation, filtration, or sand-filtration before the liquid enters the resin column to remove suspended solids.
Generally, it requires an alkali-water-acid-water flow path. For strict requirements, three circulations are recommended before reaching the final ion kernel.
