Title:
FILTER, METAL ION REMOVING METHOD, AND METAL ION REMOVING APPARATUS
Document Type and Number:
WIPO Patent Application WO/2019/138305
Kind Code:
A1
Abstract:
A filter includes a porous molding, the porous molding being a sintered product of mixed powder containing dry gel powder including an ion exchange resin and thermoplastic resin powder, or a swelled body of the sintered product. When water having an electric resistivity value of 18 MΩ･cm or more is allowed to pass through a space velocity of 1200 hr-1, the electric resistivity value of water after passage is 15 MΩ･cm or more. To provide a filter that can efficiently remove metal ions in a solution to be treated, and easily acquire a solution having an extremely low content of metal ions.
