Abstract:
The present invention relates to an iminodiacetic acid chelating resin, wherein the water amount in the resin is from 50 to 75% and the volume ratio of Na form/H form is from 1.4 to 1.8. Furthermore, the present invention relates to a method for producing an iminodiacetic acid chelating resin, wherein an alcohol is used as a solvent for the amination reaction of a chloromethylated styrene crosslinked copolymer with iminodiacetonitrile or sodium iodide and/or potassium iodide is used as a catalyst for the amination reaction.
