Abstract: Provided are a method of removing a perchlorate ion (ClO4−) and a nitrate ion (NO3−) which are toxic anions in wastewater using an anion-exchange resin on which a metal is supported, and more particularly an anion-exchange resin on which a hydrogen activating metal is supported or a hydrogen activating metal and a secondary metal are supported together and a method of removing toxic anions using the same. The toxic anions may be efficiently ion-exchanged and removed using an anion-exchange resin supporting a reduction catalyst, the regeneration of the anion-exchange resin may be facilitated, and the consumption of energy and the reducing agent may be reduced, thereby being usable in removal of toxic anions from an actual water purification system.
