Title:
ADSORPTION MEMBER AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2021/251401
Kind Code:
A1
Abstract:
Provided is an adsorption member that has exceptional adsorption capabilities with respect to foulants having relatively small molecular weights. The adsorption member has a plurality of flow paths through which treatment water passes, and a partition wall that partitions between the flow paths, wherein the wall part has a porous ceramic substrate in which are formed through-holes by which the treatment water can pass between adjacent flow paths, and a layer of metal oxide particles that are secured to the surfaces of the flow paths and the surfaces of the through-holes. In regard to the partition wall, the ratio (B/A) of the total pore specific surface area B of pores having a diameter of 6-10 nm (inclusive) as measured by mercury intrusion and the total pore specific surface area A of pores having a diameter of 1-100 nm (inclusive) as measured by gas adsorption is 49.3% or greater.
