Product Description

S400 Macroporous Iminodiacetic Chelating Resin
1. Description
S400 chelating ion-exchange resin is cross-linked polystyrene copolymer structure, the introduction of iminodiacetic acid functional group of the weak acid macroporous cation exchange resin, The selectivity of metal ions similar to EDTA, to remove it from the aqueous solution of divalent cations in order of preference is as follows: Cu²⁺>VO²⁺>UO₂²⁺>Pb²⁺>Ni²⁺>Zn²⁺>Cd²⁺>Fe²⁺>Be²⁺>Mn²⁺>Ca²⁺>Mg²⁺>Sr²⁺>Ba²⁺>Na⁺
Can be seen from the previous, S400 chelating resin demonstrated two divalent metal ions with high selectivity and high affinity. At the same time have been exchanged divalent metal ions in the low PH of the solution is easy to desorption (regeneration) so that chelation group restore exchange adsorption capabilities.
This product is equivalent to the United States: Amberlite IRC-748; Lewatit TP 207/208;
