Title:
吸着材粒子及び造粒吸着材
Document Type and Number:
Japanese Patent JP6644804
Kind Code:
B2
Abstract:
The present invention addresses the problem of providing an adsorbent that has high adsorption efficiency, that facilitates separation and collection, and that has an iron oxyhydroxide as a main component. These adsorbent particles have an average particle diameter d50 of 10-70 μm and have an iron oxyhydroxide, and preferably β-iron oxyhydroxide, as a main component. The adsorbent particles preferably comprise a dried gel that has an iron oxyhydroxide as a main component and that is generated by means of a method that includes a step for reacting an iron-compound-containing solution with a base and generating a precipitate. The adsorbent particles are preferably obtained by crushing a solid body that has an iron oxyhydroxide as a main component, separating the crushed substance in water by means of a mesh that has 5-20 μm openings, and collecting the portion that does not pass through the mesh.
