  • ALKYL-LINKED POROUS PORPHYRIN POLYMER, AND METHOD OF SEPARATING GAS AND METHOD OF RECOVERING VALUABLE METAL USING SAME
    Publication number: 20230348660
    Abstract: Disclosed are an alkyl-linked porous porphyrin polymer and gas separation and valuable metal recovery using the same, and more particularly an alkyl-linked porous porphyrin polymer imparted with a large surface area and high microporosity by linking a porphyrin unit with a chlorinated solvent linker, thereby exhibiting excellent adsorption selectivity for valuable metal to thus enable recovery of valuable metal, and also manifesting high performance in a selective gas separation method, and a method of separating gas and a method of recovering valuable metal using the same.
    Type: Application

  • Porous porphyrin polymer and method of recovering precious metal elements using the same
    Patent number: 10961343
    Abstract: A porous porphyrin polymer and a method of recovering precious metal elements using the same are described. A porous porphyrin polymer represented by Formula 1 has high selectivity for precious metal elements and a high ability to adsorb precious metal elements, and can be applied to the recovery of precious metal elements either from metal leachates of waste electronic products or from river water or seawater.
