PROBLEM TO BE SOLVED: To obtain a novel heavy metal ion adsorbent obtained by fixing a metal trapping group to a matrix resin and capable of selectively adsorbing heavy metal ions to take in them stably. SOLUTION: The heavy metal ion adsorbent comprises a reaction product of a linear copolymer having a maleic anhydride unit bonded to a porous synthetic resin through an amino group and a chelate forming compound having an amino group. This heavy metal ion adsorbent is manufactured by aminating the porous synthetic resin and subsequently the linear copolymer having the maleic anhydride unit is reacted with the aminated porous synthetic resin to form a chemical bond between the amino group in the porous synthetic resin and a part of the maleic anhydride unit and reacting the chelate forming compound having an amino group of the reaction product to introduce a chelate forming group into the obtained reaction product. |
