Weak Acid Cation Exchange Resin (WAC)
SEPLITE ® Weak Acid Cation Exchange Resin
acidic ion exchange resin? The words below would give a proper answer.
The weak acid cation exchange resin is the type of ion learning exchangeresin 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.
weakly acidic cation exchange resinsare 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 Acid Cation Exchange Resin
Bicarbonate alkalinity from water
Transition metals recovery
Water dealkalization
Purification of antibiotics and amion acid
Approvals
Kosher Certificate
Halal Certificate
