Product Description

D750 Macroporous Chelating Ion Exchange Resin

1. Description

D750 is a chelating resin with weak acid imide two acetic acid [-CH2N- (CH2OOH) 2] on the special macroporous structure of styrene and two ethylene benzene copolymers.It can immobilize and chelate one or more specific cations in a large range or even from a high concentration solution.
