Abstract
Provided is a porous molding which is capable of removing ions in water to be treated, in particular, phosphorus ions at a very high liquid-permeation rate of at least SV 120 hr−1, and which has a large adsorption capacity. The porous molding according to the present invention comprises an organic polymer resin and an inorganic ion adsorbent, and is characterized in that a total volume of pores having a pore diameter of 1-80 nm as measured by a nitrogen adsorption method is 0.05-0.7 cm3/g per unit mass of the inorganic ion adsorbent.
Claims19
A porous shaped body in which an organic polymer resin and an inorganic ion adsorbent are included, and the sum total of the volumes of pores having a pore diameter of from 1 nm to 80 nm measured by a nitrogen gas adsorption method is per unit mass of the inorganic ion adsorbent from 0.05 cm3/g to 0.7 cm3/g wherein the elastic modulus of the porous shaped body is from 1000 mN/m2 to 12000 mN/m2.
