Weak Acid Cation Exchange Resin (WAC)

SEPLITE ® Weak Acid Cation Exchange Resin

The weak acid cation exchange resin is the type of ion exchange resin with functional group of carboxylic acid group (-COOH) . They show weak acidity like acetic acid, having the ability to exchange with bases such as NaOH and weak acid salts such as NaHCO3.

The weak acid cation exchange resins have two kinds of chemical structures, a methacrylic acid type and an acrylic acid type. This makes a difference for the ion exchange ability. The methacrylic acid type can be used at pH above 5, while the acrylic acid type can be used at pH above 4. Even though use is restricted, it is easier to regenerate than a strong acid cation exchange resin.

WAC Resin are suitable in the fields of removal of water dealkalization, carbonate hardness, purification of antibiotics and amion acid. It is not used much for water processing because of the less acidity, but for antibiotic and amino acid purification.


Typical Applications For Weak Acidic Cation Exchange Resin
Bicarbonate alkalinity from water

Transition metals recovery

Water dealkalization

Purification of antibiotics and amion acid

Approvals
Kosher Certificate

Halal Certificate

FDA registeration

WQA Gold Seal Certificate

Chelating Resin

SEPLITE ® Chelating Resin SEPLITE® chelating resin  is ion exchange chelating resins for metals removal, recovery and enrichment. Chelating resins are a class of chelating ion exchange resin   with reactive functional groups that chelate to metal ions. They have the same bead form and polymer matrix as usual ion exchange resin, and the variation in chelating resins arises from the nature of chelating agents linked into a polymer backbone. SEPLITE ® Chelating resins contain a wide range of special functional groups that gives them superior selectivity for specific target metals, Such as SEPLITE®LSC710, which is the iminodiacetic acid bonded in a styrene-divinylbenzene matrix. Other functional groups bound to chelating resins are aminophosphonic acid, thiourea, 2-picolylamine and so on. Chelating resins of ion learning exchange   are almost always used to bind cations, which are found in a big range of metals removal, recovery and enrichment in a dilute solution. Chela

Strong Base Anion Exchange Resin (SBA)

SEPLITE ® Strong Base Anion Exchange Resin The Strong Base Anion Exchange Resin  ( sba resin )  is the type of ion exchange resin with functional group of quaternary ammonium, which is strongly alkaline and dissociates just like NaOH and KOH. In chemical structure, there are two types of strong base anion exchange resin with different alkalinity strengths, Type Ⅰ with a trimethyl ammonium group, Type Ⅱ with a dimethylethanol ammonium group. Type Ⅰ shows a higher alkaline than Type Ⅱ. Compared with type 1 strong base anion, this resin is more suitable for applications needing good rinsing performance and excellent regeneration efficiency. The strong base anion   shows an excellent physical and chemical stability, which is capable of exchanging the different anion under a wide range of pH. The Strong Base Anion Exchange Resin is mainly used in water treatment, to produce high purity demineralized water, making use of the ability to adsorb anions strongly. Typical App
