Weak Acid Cation Exchange Resin

Alfa Chemistry is a new industry and new material technology company integrating R&D, resin production, sales, service. We supply various types of ion exchange resins.

Weak acid cation resins are available in hydrogen form (R-COOH), and they have high affinity for hydrogen ions. They show weak acidity like acetic acid, having the ability to exchange with bases such as NaOH and weak acid salts such as NaHCO₃. They are used in a wide variety of fields including bicarbonate alkalinity from water, transition metals recovery, water de-alkalization, purification of antibiotics and amino acid.

Here lists our weak acid cation exchange resins and their technical data. Please feel free to contact us for more details.
