The application for the patent was published on June 05, 2026, under issue no. 23/2026.
Abstract: The present invention addresses the problem of providing a method for producing (regenerating) an adsorbing material or recovering a target substance by adsorbing the target substance to the adsorbing material and then performing a desorption treatment on the target substance, the method being capable of desorbing a sufficient amount of the target substance without using aqua regia in the desorption treatment, and being capable of preventing a decrease in the adsorption performance of the adsorbing material after the desorption treatment. To solve the problem, provided is a method for producing an adsorbing material or a method for recovering a target substance, the method comprising: (1) a step for preparing a second adsorbing material obtained by performing a contact treatment with a target substance-containing liquid on a first adsorbing material which has a co-continuous structure formed by macropores and a ceramic skeleton having mesopores and in which the surface of the ceramic skeleton is modified with a functional group capable of adsorbing a target substance; and (2) a step for obtaining a third adsorbing material or a target substance by performing a contact treatment with an acidic solution excluding aqua regia on the second adsorbing material to desorb the target substance from the second adsorbing material.
