  • Porous molding
    Patent number: 11865509
    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.
    Type: Grant
    Filed: December 21, 2018
    Date of Patent: January 9, 2024
    Assignee: Asahi Kasei Kabushiki Kaisha
    Inventors: Masashi Kogawa, Keitaro Suzumura, Yutaka Koyama
  • Phosphate adsorbing agent for blood processing, blood processing system and blood processing method
    Patent number: 11224871
    Abstract: The present invention provides a phosphate adsorbing agent for blood processing comprising a porous formed article comprising an organic polymer resin and an inorganic ion adsorbent and having a most frequent pore size of 0.08 to 0.70 ?m measured with a mercury porosimeter, the phosphate adsorbing agent for blood processing having a biocompatible polymer in the surface of the porous formed article.
