High quality cation exchange resin

The resin have two types:cation exchange resin and anion exchange resin.

Below is one of Lanlang's cation exchange resin:TC113D WAC resin.

In addition,it is a macroporous type resin.

Physical and chemical properties

The macroporous resin is also called a fully porous resin, and the macroporous resin is prepared by polymerization of an additive such as a polymerization monomer and a crosslinking agent, a porogen, and a dispersant. After the formation of the polymer, the porogen is removed, leaving pores of various sizes, shapes, and interpenetration in the resin. Therefore, the macroporous resin has a high porosity inside in a dry state and a large pore diameter of between 100 and 1000 nm, so it is called a macroporous adsorption resin.

The macroporous adsorption resin selectively adsorbs organic substances from the solution by physical adsorption, thereby achieving separation and purification. Its physicochemical properties are stable, insoluble in acids, bases and organic solvents. It has good selectivity to organic matter, is not affected by the presence of inorganic salts and strong ions and low molecular compounds, and can be adsorbed by swelling in water and organic solvents.

Adsorption capacity

The cation exchange resin has different adsorption capacities for different cations present in the solution. Generally, the adsorption capacity for high-valent ions is greater than that for low-valent ions; the same-valent ions have higher adsorption capacity for large-diameter ions than for small-diameter ions. ability.

The order of adsorption capacity of common cations is as follows:

Fe3+ > Al3+ > Pb2+ > Ca2+ > Mg2+ > K+ > Na+ > H+
