    摘要: A process for producing a resin for the chromatographic extraction of metal ions is provided, the process involving:treating an acidic bidentate organic phosphonate metal complexing agent with an alcohol or ketone solvent containing an aqueous alkaline solution, thereby forming the corresponding salt of the phosphonate compound;mixing the bidentate organic phosphonate salt with an absorbent resin in an alcohol or ketone solvent containing an aqueous alkaline solution, thereby absorbing the phosphonate salt in the resin;washing the resin containing bidentate complexing agent with an aqueous alcohol or ketone solution; anddrying the washed resin, wherein the process provides improved chromatographic extraction of metal ions.
