To obtain an adsorbent capable of adsorbing and recovering useful rare metals, especially gold, without having an issue of environmental pollution and excellent in adsorbing and recovering performance.
The subject method for synthesizing the adsorbent capable of adsorbing and recovering useful rare metals dissolved in a solution comprises forming reaction active points on a polymer substrate, then forming graft chains by polymerizing a reactive monomer by a graft polymerization method to introduce chelate-forming groups. In this method, the polymer substrate is produced from a woven fabric, non-woven fabric, film, hollow fiber membrane or yarn containing a polyolefin-based fiber such as of a polyethylene, polypropylene, as a raw material, and the reactive monomer is a vinyl reactive monomer selected from the group consisting of allylamine, glycidyl methacrylate, glycidyl acrylate or their mixture.
