An object of the present invention is to provide a molded article carrying a phosphorus adsorbent and useful for purification of a liquid to be treated, and a method for purifying the liquid to be treated using the same. The present invention relates to a molded article obtained by bringing a solution containing a polymer, a solvent and a metal hydroxide into contact with a coagulating liquid and solidifying the metal hydroxide, wherein the metal hydroxide has the following formula (1): M 2+ 1-x M 3+ x (OH − ) 2 + xy (A n− ) y / n (1) ( Wherein M 2+ is selected from the group consisting of Mg 2+ , Ni 2+ , Zn 2+ , Fe 2+ , Ca 2+ and Cu 2+ , M 3+ is selected from the group consisting of Al 3+ and Fe 3+ , and An -. represents an n-valent anion is 0.1 ≦ x ≦ 0.5, a 0.1 ≦ y ≦ 0.5, n is represented by 1 or 2), and metal hydroxide A molded product having an average particle size of 0.05 to 100 μm and a method for purifying a liquid to be treated using the molded product.
