Abstract

A porous formed article includes an organic polymer resin and an inorganic ion adsorbent and having the most frequent pore size of 0.08 to 0.70 μm measured with a mercury porosimeter. Such a porous formed article can be prepared by crushing and mixing a good solvent for the organic polymer resin and the inorganic ion adsorbent to obtain slurry; dissolving the organic polymer resin and a water-soluble polymer in the slurry; shape-forming the slurry; promoting coagulation of the shape-formed product by controlling the temperature and humidity of a spatial portion coming into contact with the shape-formed product, until the shape-formed product is coagulated in a poor solvent; and coagulating the coagulation-promoted shape-formed product in a poor solvent. A production apparatus can be used to prepare such a porous formed article.
