PROBLEM TO BE SOLVED: To provide a molding having a phosphorus adsorbent supported thereon and useful for purifying a liquid to be treated, and a purification method of the liquid to be treated using it. SOLUTION: The molding is produced by bringing a solution, which contains a polymer, a solvent and a metal hydroxide into contact with a coagulation liquid to coagulate the same. The metal hydroxide is represented by the formula (1): M<SP>2+</SP><SB>1-x</SB>M<SP>3+</SP><SB>x</SB>(OH<SP>-</SP>)<SB>2+x-y</SB>(A<SP>n-</SP>)<SB>y/n</SB>(wherein M<SP>2+</SP>is selected from the group consisting of Mg<SP>2+</SP>, Ni<SP>2+</SP>, Zn<SP>2+</SP>, Fe<SP>2+</SP>, Ca<SP>2+</SP>and Cu<SP>2+</SP>, M<SP>3+</SP>is selected from the group consisting of Al<SP>3+</SP>and Fe<SP>3+</SP>, A<SP>n-</SP>is an n-valent anion, x is 0.1≤x≤0.5, y is 0.1≤y≤0.5 and n is 1 or 2) and the average particle size of the metal hydroxide is 0.05-100μm. The purification method of the liquid to be treated using it is also disclosed. COPYRIGHT: (C)2007,JPO&INPIT |
