The Strong Acid Cation Exchange Resin 001X7 (0.8-1.6mm) is a high-capacity, gel-type copolymer produced from styrene and divinylbenzene (DVB). Engineered for superior ion-exchange performance, this resin features sulfonic acid functional groups, ensuring exceptional efficiency in removing multivalent cations from aqueous solutions.
Designed for versatility and durability, the 001X7 resin is widely utilized in critical industrial processes, including industrial water softening, the production of high-purity water, wet metallurgy, and the precise separation of rare elements. Its optimized particle size distribution and high exchange capacity make it a reliable alternative to industry benchmarks like Amberlite IRA-120 and Dowex 50KY2-8.

It is primarily used for water softening, pure water preparation, and in wet metallurgy for the separation of rare elements and metal recovery.
Resin should be kept in a closed space in a wet state. For long-term storage, adding a salt solution of 5% or higher is recommended to maintain activity.
The resin is typically regenerated using 3-5% Hydrochloric Acid (HCl) for desorption and 2-4% Sodium Hydroxide (NaOH) for specific transformations.
Yes, the 001X7 resin is designed for high thermal stability with a maximum operating temperature of 120℃.
It is essential to implement pre-treatment steps such as flocculation, filtration, or sand-filtration to remove suspended solids before the liquid enters the resin column.
A uniformity coefficient of ≤ 1.6 indicates consistent bead sizing, which optimizes flow distribution and minimizes pressure drop across the resin bed.
