D113 Macroporous Weak Acid Cation Exchange Resin
详细说明
1. Description
D113 is a premium grade, weak acid, macroporous, cation resin supplied in the hydrogen form as moist, tough, uniform, spherical beads. Its ion exchange functionality is derived from the carboxylic group, which is easily converted to the hydrogen form and has a high affinity for divalent ions.D113 is intended for use in hydrogen cycle dealkalization, deionization, and chemical processing applications. D113 can also be supplied in the sodium form for use in sodium cycle applications such as softening and removal of heavy metal cations.

4.Applications
Use in the deionization and softening of water and aqueous organic solutions,with 001x7 strongly acidic cation exchange resin can remove alkalinity and hardness from water obviously,especially removing hydrogen carbonates, carbonates and other alkali salts. It is also used in industrial wastewater treatment, metal recycling, separation and purification of biochemical pharmaceuticals etc.
