Resinex CH-23 UB
™
Weak acidic cation exchange resin
Resinex™ CH-23 UB is a high purity, premium grade, weakly acidic macroporous type cation exchange resin with chelating
groups. This product is designed to be used in industrial applications for the selective extraction of heavy metal cations in
the following order: Cu - Va - U - Pb - Ni - Zn - Cd - Fe - Be - Mn - Ca - Mg - Sr - Ba - Na
Resinex™ CH-23 UB offers a superior mechanical and chemical resistance which guaranty an economical
advantage and an extended lifetime. The uniform bead size distribution provides a low pressure drop during the
service run.
