Description

S400 The chelating type ion exchange resin is a weakly acidic macroporous cation exchange resin which introduces an iminodiacetic acid functional group on a crosslinked polystyrene copolymer, and the resin can selectively extract a divalent heavy metal cation from an aqueous solution because the resin Having an iminodiacetic acid chelating group, the selectivity to metal ions is similar to EDTA, and the order of selection for removing divalent cations from aqueous solution is as follows: Cu2+﹥VO2+﹥UO22+﹥Pb2+﹥Ni2+﹥Zn2+﹥Cd2+﹥Fe2+﹥Be2+﹥Mn2+﹥Ca2+﹥Mg2+﹥Sr2+﹥Ba2+﹥Na+

As can be seen from the above, the S400 chelating resin exhibits high selectivity and high affinity for divalent metal ions. At the same time, the divalent metal ions exchanged are easily desorbed (regenerated) in a low pH solution, and the chelating groups are restored to the exchange adsorption function.
