An ion-exchange zone can be kept short, the volume of an ion-exchanger can be reduced, and a small leak of adsorbed ions does not occur, so that the frequency of regeneration is reduced and the processing efficiency is improved. To provide an ion adsorption module and a water treatment method that can be used. A container having at least an opening into which water to be treated flows, an open cell structure having macropores connected to each other filled in the container and mesopores having an average diameter of 1 to 1000 µm in the walls of the macropores. An organic porous material having a three-dimensional network structure in which the total pore volume is 1 ml / g to 50 ml / g, the ion exchange groups are uniformly distributed, and the ion exchange capacity is 0.5 mg equivalent / g or more of the dry porous material. An ion adsorption module comprising a porous ion exchanger. [Selection diagram] None |
