PROBLEM TO BE SOLVED: To provide a porous molding which can adsorb/remove low concentration of phosphorus, boron, fluorine, arsenic or the like, that is contained in sewage or waste water, at a high speed and which is suitable as an adsorbent having a large adsorption capacity.SOLUTION: The porous molding contains an organic polymer resin and an inorganic ion adsorbing body, is obtained by using an electron probe microanalyzer (EPMA) and is characterized in that a ratio (a relatively cumulative X-ray intensity ratio) of 95%-relatively cumulative X-ray intensity, which is of a constituent element constituting the inorganic ion adsorbing body to be deposited on the porous molding, to 5%-relatively cumulative X-ray intensity thereof is within 1-10. |
