PURPOSE: An ion exchange resin for recovering indium with excellent swelling performance and absorptivity because indium can be moderately collect from seawater. CONSTITUTION: A manufacturing method of an ion exchange resin for recovering indium comprises: a step of suspension polymerization of an acrylic acid monomer indicated in chemical formula 1 and poly(ethylene glycol) diacrylate indicated in chemical formula 2. In chemical formulas, R1 is H or a methyl group and n is an integer from 7-14. A solvent of an initiator is toluene. The acrylic acid monomer is 16-20 weight% based on total weight of ion exchange resin for indium collection.
