D301FC weakly basic anion exchange resin

High valence ions are usually preferentially adsorbed, while low valence ions have weaker adsorption. Among ions of the same valence, ions with larger diameters are more strongly adsorbed. The order in which some cations are adsorbed is as follows:

Fe3+ > Al3+ > Ra2+ > Pb2+ > Sr2+ > Ca2+ >Ni2+ > Cd2+ > Cu2+ > Co2+ > Zn2+ > Mg2+>Ba2+ > K+ > NH4+>Na+ > Li+

For strongly acidic cation resins, the selectivity of H+is between Na+and Li+. But for weakly acidic cation resins, H+has strong selectivity.

The coagulation filtration method of the present invention involves adding cationic coagulants to the treated water for coagulation treatment, and then using a filter with at least a portion of the filter material set as cation exchange resin for filtration, wherein a weakly acidic cation exchange resin is used as the cation exchange resin. When the filtered water quality from the filter exceeds the specified value, the weakly acidic cation exchange resin is regenerated.
