• Copper ions on several kinds of cation exchange resins were investigated by means of ESR spectroscopy. It was found that the motion of copper ions is restricted in the network of the ion exchange resin, and that the mobility of copper ions is closely connected with the chemical interaction of the copper ions with the fixed ionic groups of the resins. The mobility of copper ions is in the order of; on the sulfonic group>on the phosphonic group>on the carboxylic group>on the iminodiacetate group. This sequence is the reverse of the selectivity for the copper ion. The effect of the water molecules involved in ion exchange resins is also considered, and the copper species on each ion exchange resin are assumed.
